The Mark of Athena (The Heroes of Olympus, Book Three) (34 page)

Annabeth figured it could’ve been worse.
If she had to go on a horrifying solo quest, at least she’d
gotten to have lunch with Percy on the banks of the Tiber first. Now she got to take a scooter ride with Gregory Peck.

She only knew about that old movie because of her dad. Over the past few years, since the two of them had made up, they’d spent more time together, and she had learned that her dad had a sappy side. Sure, he liked military history, weapons, and biplanes, but he also loved old films, especially romantic comedies from the 1940s and ’50s.
Roman Holiday
was one of his favorites. He’d made Annabeth watch it.

She thought the plot was silly—a princess escapes her minders and falls in love with an American journalist in Rome—but she suspected her dad liked it because it reminded him of his own romance with the goddess Athena: another impossible pairing that couldn’t end happily. Her dad was nothing like Gregory Peck. Athena certainly wasn’t anything like Audrey Hepburn. But Annabeth knew that people saw what they wanted to see. They didn’t need the Mist to warp their perceptions.

As the baby-blue scooter zipped through the streets of Rome, the goddess Rhea Silvia gave Annabeth a running commentary on how the city had changed over the centuries.

“The Sublician Bridge was over there,” she said, pointing to a bend in the Tiber. “You know, where Horatius and his two friends defended the city from an invading army? Now,
there
was a brave Roman!”

“And look, dear,” Tiberinus added, “that’s the place where Romulus and Remus washed ashore.”

He seemed to be talking about a spot on the riverside where some ducks were making a nest out of torn-up plastic bags and candy wrappers.

“Ah, yes,” Rhea Silvia sighed happily. “You were so kind to flood yourself and wash my babies ashore for the wolves to find.”

“It was nothing,” Tiberinus said.

Annabeth felt light-headed. The river god was talking about something that had happened thousands of years ago, when this area was nothing but marshes and maybe some shacks. Tiberinus saved two babies, one of whom went on to found the world’s greatest empire.
It was nothing.

Rhea Silvia pointed out a large modern apartment building. “That used to be a temple to Venus. Then it was a church. Then a palace. Then an apartment building. It burned down three times. Now it’s an apartment building again. And that spot right there—”

“Please,” Annabeth said. “You’re making me dizzy.”

Rhea Silvia laughed. “I’m sorry, dear. Layers upon layers of history here, but it’s nothing compared to Greece. Athens was old when Rome was a collection of mud huts. You’ll see, if you survive.”

“Not helping,” Annabeth muttered.

“Here we are,” Tiberinus announced. He pulled over in front of a large marble building, the facade covered in city grime but still beautiful. Ornate carvings of Roman gods decorated the roofline. The massive entrance was barred with iron gates, heavily padlocked.

“I’m going in there?” Annabeth wished she’d brought Leo, or at least borrowed some wire cutters from his tool belt.

Rhea Silvia covered her mouth and giggled. “No, my dear. Not
in
it.
Under
it.”

Tiberinus pointed to a set of stone steps on the side of the building—the sort that would have led to a basement apartment if this place were in Manhattan.

“Rome is chaotic aboveground,” Tiberinus said, “but that’s nothing compared to
below
ground. You must descend into the buried city, Annabeth Chase. Find the altar of the foreign god. The failures of your predecessors will guide you. After that…I do not know.”

Annabeth’s backpack felt heavy on her shoulders. She’d been studying the bronze map for days now, scouring Daedalus’s laptop for information. Unfortunately, the few things she had learned made this quest seem even more impossible. “My siblings…none of them made it all the way to the shrine, did they.”

Tiberinus shook his head. “But you know what prize awaits, if you can liberate it.”

“Yes,” Annabeth said.

“It could bring peace to the children of Greece and Rome,” Rhea Silvia said. “It could change the course of the coming war.”

“If I live,” Annabeth said.

Tiberinus nodded sadly. “Because you also understand the guardian you must face?”

Annabeth remembered the spiders at Fort Sumter, and the dream Percy had described—the hissing voice in the dark. “Yes.”

Rhea Silvia looked at her husband. “She is brave. Perhaps she is stronger than the others.”

“I hope so,” said the river god. “Good-bye, Annabeth Chase. And good luck.”

Rhea Silvia beamed. “We have such a lovely afternoon planned! Off to shop!”

Gregory Peck and Audrey Hepburn sped off on their baby-blue motorbike. Then Annabeth turned and descended the steps alone.

She’d been underground plenty of times.

But halfway down the steps, she realized just how long it had been since she’d adventured by herself. She froze.

Gods…she hadn’t done something like this since she was a
kid.
After running away from home, she’d spent a few weeks surviving on her own, living in alleyways and hiding from monsters until Thalia and Luke took her under their wings. Then, once she’d arrived at Camp Half-Blood, she’d lived there until she was twelve. After that, all her quests had been with Percy or her other friends.

The last time she had felt this scared and alone, she’d been seven years old. She remembered the day Thalia, Luke, and she had wandered into a Cyclopes’ lair in Brooklyn. Thalia and Luke had gotten captured, and Annabeth had had to cut them free. She still remembered shivering in a dark corner of that dilapidated mansion, listening to the Cyclopes mimicking her friends’ voices, trying to trick her into coming out into the open.

What if
this
is a trick, too? she wondered. What if those other children of Athena died because Tiberinus and Rhea Silvia led them into a trap? Would Gregory Peck and Audrey Hepburn do something like that?

She forced herself to keep going. She had no choice. If the Athena Parthenos was really down here, it could decide the fate of the war. More importantly, it could help her mom. Athena
needed
her.

At the bottom of the steps she reached an old wooden door with an iron pull ring. Above the ring was a metal plate with a keyhole. Annabeth started considering ways to pick the lock, but as soon as she touched the pull ring, a fiery shape burned in the middle of the door: the silhouette of Athena’s owl. Smoke plumed from the keyhole. The door swung inward.

Annabeth looked up one last time. At the top of the stairwell, the sky was a square of brilliant blue. Mortals would be enjoying the warm afternoon. Couples would be holding hands at the cafés. Tourists would be bustling through the shops and museums. Regular Romans would be going about their daily business, probably not considering the thousands of years of history under their feet, and definitely unaware of the spirits, gods, and monsters that still dwelt here, or the fact that their city might be destroyed today unless a certain group of demigods succeeded in stopping the giants.

Annabeth stepped through the doorway.

She found herself in a basement that was an architectural cyborg. Ancient brick walls were crisscrossed with modern electrical cables and plumbing. The ceiling was held up with a combination of steel scaffolding and old granite Roman columns.

The front half of the basement was stacked with crates. Out of curiosity, Annabeth opened a few. Some were packed with multicolored spools of string—like for kites or arts and crafts projects. Other crates were full of cheap plastic gladiator swords. Maybe at one point this had been a storage area for a tourist shop.

In the back of the basement, the floor had been excavated, revealing another set of steps—these of white stone—leading still deeper underground.

Annabeth crept to the edge. Even with the glow cast by her dagger, it was too dark to see below. She rested her hand on the wall and found a light switch.

She flipped it. Glaring white fluorescent bulbs illuminated the stairs. Below, she saw a mosaic floor decorated with deer and fauns—maybe a room from an Ancient Roman villa, just stashed away under this modern basement along with the crates of string and plastic swords.

She climbed down. The room was about twenty feet square. The walls had once been brightly painted, but most of the frescoes had peeled or faded. The only exit was a hole dug in one corner of the floor where the mosaic had been pulled up. Annabeth crouched next to the opening. It dropped straight down into a larger cavern, but Annabeth couldn’t see the bottom.

She heard running water maybe thirty or forty feet below. The air didn’t smell like a sewer—just old and musty, and slightly sweet, like moldering flowers. Perhaps it was an old water line from the aqueducts. There was no way down.

“I’m not jumping,” she muttered to herself.

As if in reply, something glowed in the darkness. The Mark of Athena blazed to life at the bottom of the cavern, revealing glistening brickwork along a subterranean canal forty feet below. The fiery owl seemed to be taunting her:
Well, this is the way, kid. So you
’d
better figure something out.

Annabeth considered her options. Too dangerous to jump. No ladders or ropes. She thought about borrowing some metal scaffolding from above to use as a fire pole, but it was all bolted in place. Besides, she didn’t want to cause the building to collapse on top of her.

Frustration crawled through her like an army of termites. She had spent her life watching other demigods gain amazing powers. Percy could control water. If he were here, he could raise the water level and simply float down. Hazel, from what she had said, could find her way underground with flawless accuracy and even create or change the course of tunnels. She could easily make a new path. Leo would pull just the right tools from his belt and build something to do the job. Frank could turn into a bird. Jason could simply control the wind and float down. Even Piper with her charmspeak…she could have convinced Tiberinus and Rhea Silvia to be a little more helpful.

What did Annabeth have? A bronze dagger that did nothing special, and a cursed silver coin. She had her backpack with Daedalus’s laptop, a water bottle, a few pieces of ambrosia for emergencies, and a box of matches—probably useless, but her dad had drilled into her head that she should always have a way to make fire.

She had no amazing powers. Even her one true magic item, her New York Yankees cap of invisibility, had stopped working, and was still back in her cabin on the
Argo II
.

You’ve got your intelligence,
a voice said. Annabeth wondered if Athena was speaking to her, but that was probably just wishful thinking.

Intelligence…like Athena’s favorite hero, Odysseus. He’d won the Trojan War with cleverness, not strength. He had overcome all sorts of monsters and hardships with his quick wits. That’s what Athena valued.

Wisdom’s
daughter walks alone.

That didn’t mean just without other people, Annabeth realized. It meant without any special powers.

Okay…so how to get down there safely and make sure she had a way to get out again if necessary?

She climbed back to the basement and stared at the open crates. Kite string and plastic swords. The idea that came to her was so ridiculous, she almost had to laugh; but it was better than nothing.

She set to work. Her hands seemed to know exactly what to do. Sometimes that happened, like when she was helping Leo with the ship’s machinery or drawing architectural plans on the computer. She’d never made anything out of kite string and plastic swords, but it seemed easy, natural. Within minutes she’d used a dozen balls of string and a crateful of swords to create a makeshift rope ladder—a braided line, woven for strength yet not too thick, with swords tied at two-foot intervals to serve as hand- and footholds.

As a test, she tied one end around a support column and leaned on the rope with all her weight. The plastic swords bent under her, but they provided some extra bulk to the knots in the cord, so at least she could keep a better grip.

The ladder wouldn’t win any design awards, but it might get her to the bottom of the cavern safely. First, she stuffed her backpack with the leftover spools of string. She wasn’t sure why, but they were one more resource, and not too heavy.

She headed back to the hole in the mosaic floor. She secured one end of her ladder to the nearest piece of scaffolding, lowered the rope into the cavern, and shinnied down.

As Annabeth hung in the air,
descending hand over hand with the ladder swinging wildly, she thanked Chiron for all those years of training on the climbing course at Camp Half-Blood
. She’d
complained loudly and often that rope climbing would never help her defeat a monster. Chiron had just smiled, like he knew this day would come.

Finally Annabeth made it to the bottom. She missed the brickwork edge and landed in the canal, but it turned out to be only a few inches deep. Freezing water soaked into her running shoes.

She held up her glowing dagger. The shallow channel ran down the middle of a brickwork tunnel. Every few yards, ceramic pipes jutted from the walls. She guessed that the pipes were drains, part of the ancient Roman plumbing system, though it was amazing to her that a tunnel like this had survived, crowded underground with all the other centuries’ worth of pipes, basements, and sewers.

A sudden thought chilled her even more than the water. A few years ago, Percy and she had gone on a quest in Daedalus’s labyrinth—a secret network of tunnels and rooms, heavily enchanted and trapped, which ran under all the cities of America.

When Daedalus died in the Battle of the Labyrinth, the entire maze had collapsed—or so Annabeth believed. But what if that was only in America? What if this was an older version of the labyrinth? Daedalus once told her that his maze had a life of its own. It was constantly growing and changing. Maybe the labyrinth could regenerate, like monsters. That would make sense. It was an archetypal force, as Chiron would say—something that could never really die.

If this was part of the labyrinth…

Annabeth decided not to dwell on that, but she also decided not to assume her directions were accurate. The labyrinth made distance meaningless. If she wasn’t careful, she could walk twenty feet in the wrong direction and end up in Poland.

Just to be safe, she tied a new ball of string to the end of her rope ladder. She could unravel it behind her as she explored. An old trick, but a good one.

She debated which way to go. The tunnel seemed the same in both directions. Then, about fifty feet to her left, the Mark of Athena blazed against the wall. Annabeth could swear it was glaring at her with those big fiery eyes, as if to say,
What’s
your problem? Hurry up!

She was really starting to hate that owl.

By the time she reached the spot, the image had faded, and she’d run out of string on her first spool.

As she was attaching a new line, she glanced across the tunnel. There was a broken section in the brickwork, as if a sledgehammer had knocked a hole in the wall. She crossed to take a look. Sticking her dagger through the opening for light, Annabeth could see a lower chamber, long and narrow, with a mosaic floor, painted walls, and benches running down either side. It was shaped sort of like a subway car.

She stuck her head into the hole, hoping nothing would bite it off. At the near end of the room was a bricked-off doorway. At the far end was a stone table, or maybe an altar.

Hmm…The water tunnel kept going, but Annabeth was sure this was the way. She remembered what Tiberinus had said:
Find the altar of the foreign god.
There didn’t seem to be any exits from the altar room, but it was a short drop onto the bench below. She should be able to climb out again with no problem.

Still holding her string, she lowered herself down.

The room’s ceiling was barrel-shaped with brick arches, but Annabeth didn’t like the look of the supports. Directly above her head, on the arch nearest to the bricked-in doorway, the capstone was cracked in half. Stress fractures ran across the ceiling. The place had probably been intact for two thousand years, but she decided she’d rather not spend too much time here. With her luck, it would collapse in the next two minutes.

The floor was a long narrow mosaic with seven pictures in a row, like a time line. At Annabeth’s feet was a raven. Next was a lion. Several others looked like Roman warriors with various weapons. The rest were too damaged or covered in dust for Annabeth to make out details. The benches on either side were littered with broken pottery. The walls were painted with scenes of a banquet: a robed man with a curved cap like an ice cream scoop, sitting next to a larger guy who radiated sunbeams. Standing around them were torchbearers and servants, and various animals like crows and lions wandered in the background. Annabeth wasn’t sure what the picture represented, but it didn’t remind her of any Greek legends that she knew.

At the far end of the room, the altar was elaborately carved with a frieze showing the man with the ice-cream-scoop hat holding a knife to the neck of a bull. On the altar stood a stone figure of a man sunk to his knees in rock, a dagger and a torch in his outraised hands. Again, Annabeth had no idea what those images meant.

She took one step toward the altar. Her foot went
CRUNCH.
She looked down and realized she’d just put her shoe through a human rib cage.

Annabeth swallowed back a scream. Where had
that
come from? She had glanced down only a moment before and hadn’t seen any bones. Now the floor was littered with them. The rib cage was obviously old. It crumbled to dust as she removed her foot. Nearby lay a corroded bronze dagger very much like her own. Either this dead person had been carrying the weapon, or it had killed him.

She held out her blade to see in front of her. A little farther down the mosaic path sprawled a more complete skeleton in the remains of an embroidered red doublet, like a man from the Renaissance. His frilled collar and skull had been badly burned, as if the guy had decided to wash his hair with a blowtorch.

Wonderful, Annabeth thought. She lifted her eyes to the altar statue, which held a dagger and a torch.

Some kind of test, Annabeth decided. These two guys had failed. Correction: not just two guys. More bones and scraps of clothing were scattered all the way to the altar. She couldn’t guess how many skeletons were represented, but she was willing to bet they were all demigods from the past, children of Athena on the same quest.

“I will not be another skeleton on your floor,” she called to the statue, hoping she sounded brave.

A girl,
said a watery voice, echoing through the room.
Girls are not allowed.

A female demigod,
said a second voice.
Inexcusable.

The chamber rumbled. Dust fell from the cracked ceiling. Annabeth bolted for the hole she’d come through, but it had disappeared. Her string had been severed. She clambered up on the bench and pounded on the wall where the hole had been, hoping the hole’s absence was just an illusion, but the wall felt solid.

She was trapped.

Along the benches, a dozen ghosts shimmered into existence—glowing purple men in Roman togas, like the Lares she’d seen at Camp Jupiter. They glared at her as if she’d interrupted their meeting.

She did the only thing she could. She stepped down from the bench and put her back to the bricked-in doorway. She tried to look confident, though the scowling purple ghosts and the demigod skeletons at her feet made her want to turtle in her T-shirt and scream.

“I’m a child of Athena,” she said, as boldly as she could manage.

“A Greek,” one of the ghosts said with disgust. “That is even worse.”

At the other end of the chamber, an old-looking ghost rose with some difficulty (do ghosts have arthritis?) and stood by the altar, his dark eyes fixed on Annabeth. Her first thought was that he looked like the pope. He had a glittering robe, a pointed hat, and a shepherd’s crook.

“This is the cavern of Mithras,” said the old ghost. “You have disturbed our sacred rituals. You cannot look upon our mysteries and live.”

“I don’t want to look upon your mysteries,” Annabeth assured him. “I’m following the Mark of Athena. Show me the exit, and I’ll be on my way.”

Her voice sounded calm, which surprised her. She had no idea how to get out of here, but she knew she had to succeed where her siblings had failed. Her path led farther
on
—
deeper
into the underground layers of Rome.

The failures of your predecessors will guide you,
Tiberinus had said
. After that…I do not know.

The ghosts mumbled to each other in Latin. Annabeth caught a few unkind words about female demigods and Athena.

Finally the ghost with the pope hat struck his shepherd’s crook against the floor. The other Lares fell silent.

“Your Greek goddess is powerless here,” said the pope. “Mithras is the god of Roman warriors! He is the god of the legion, the god of the empire!”

“He wasn’t even Roman,” Annabeth protested. “Wasn’t he, like, Persian or something?”

“Sacrilege!” the old man yelped, banging his staff on the floor a few more times. “Mithras protects us! I am the
pater
of this brotherhood—”

“The father,” Annabeth translated.

“Do not interrupt! As
pater
, I must protect our mysteries.”

“What mysteries?” Annabeth asked. “A dozen dead guys in togas sitting around in a cave?”

The ghosts muttered and complained, until the
pater
got them under control with a taxicab whistle. The old guy had a good set of lungs. “You are clearly an unbeliever. Like the others, you must die.”

The others.
Annabeth made an effort not to look at the skeletons.

Her mind worked furiously, grasping for anything she knew about Mithras. He had a secret cult for warriors. He was popular in the legion. He was one of the gods who’d supplanted Athena as a war deity. Aphrodite had mentioned him during their teatime chat in Charleston. Aside from that, Annabeth had no idea. Mithras just wasn’t one of the gods they talked about at Camp Half-Blood. She doubted the ghosts would wait while she whipped out Daedalus’s laptop and did a search.

She scanned the floor mosaic—seven pictures in a row. She studied the ghosts and noticed all of them wore some sort of badge on their toga—a raven, or a torch, or a bow.

“You have rites of passage,” she blurted out. “Seven levels of membership. And the top level is the
pater
.”

The ghosts let out a collective gasp. Then they all began shouting at once.

“How does she know this?” one demanded.

“The girl has gleaned our secrets!”

“Silence!” the
pater
ordered.

“But she might know about the ordeals!” another cried.

“The ordeals!” Annabeth said. “I know about them!”

Another round of incredulous gasping.

“Ridiculous!” The
pater
yelled. “The girl lies! Daughter of Athena, choose your way of death. If you do not choose, the god will choose for you!”

“Fire or dagger,” Annabeth guessed.

Even the
pater
looked stunned. Apparently he hadn’t remembered there were victims of past punishments lying on the floor.

“How—how did you… ?” He gulped. “Who
are
you?”

“A child of Athena,” Annabeth said again. “But not just any child. I am…uh, the
mater
in my sisterhood. The
magna mater
, in fact. There are no mysteries to me. Mithras cannot hide anything from my sight.”

“The
magna mater
!” a ghost wailed in despair. “The big mother!”

“Kill her!” One of the ghosts charged, his hands out to strangle her, but he passed right through her.

“You’re dead,” Annabeth reminded him. “Sit down.”

The ghost looked embarrassed and took his seat.

“We do not need to kill you ourselves,” the
pater
growled. “Mithras shall do that for us!”

The statue on the altar began to glow.

Annabeth pressed her hands against the bricked-in doorway at her back. That
had
to be the exit. The mortar was crumbling, but it was not weak enough for her to break through with brute force.

She looked desperately around the
room
—
the
cracked ceiling, the floor mosaic, the wall paintings, and the carved altar. She began to talk, pulling deductions from the top of her head.

“It is no good,” she said. “I know all. You test your initiates with fire because the torch is the symbol of Mithras. His other symbol is the dagger, which is why you can also be tested with the blade. You want to kill me, just as…uh, as Mithras killed the sacred bull.”

It was a total guess, but the altar showed Mithras killing a bull, so Annabeth figured it must be important. The ghosts wailed and covered their ears. Some slapped their faces as if to wake up from a bad dream.

“The big mother knows!” one said. “It is impossible!”

Unless you look around the room, Annabeth thought, her confidence growing.

She glared at the ghost who had just spoken. He had a raven badge on his toga—the same symbol as on the floor at her feet.

“You are just a raven,” she scolded. “That is the lowest rank. Be silent and let me speak to your
pater
.”
