The Dark Prophecy by Rick Riordan

Pretty fuzzy cow

So cute, so warm and vicious!

Squee! Can I kill him?

TRIUMVIRATE HOLDINGS

Commodus and his colleagues may have been power-hungry murderers bent on world domination, but at least they cared about cleaning up litter.

Along the roadside ran a barbed-wire fence. Beyond this lay more nondescript countryside—a few stands of trees and shrubs, but mostly rolling meadows. In the predawn light, dew exhaled a blanket of vapor over the grass. In the distance, behind a clump of hackberry bushes, two large animals stood grazing. I couldn’t make out their exact forms. They looked like cows. I doubted they were cows. I spotted no other guardians, killable or otherwise, which did not reassure me in the slightest.

“Well,” I told Meg. “Shall we?”

We shouldered our supplies and left the Mercedes.

Meg removed her jacket and laid it across the barbed wire. Despite the arrow’s instructions to jumpest, we only managed a wobbly giant steppeth. I held down the top wire for Meg, then she failed to do the same for me. This left me with some awkward rips in the seat of my jeans.

We sneaked across the field in the direction of the two grazing beasts.

I was sweating an unreasonable amount. The cold morning air condensed on my skin, making me feel as if I were bathing in a cold soup—Apollo gazpacho. (Hmm, that sounded rather good. I will have to trademark it once I become a god again.)

We crouched behind the hackberries, only twenty or thirty feet from the animals. Dawn tinged the horizon with red.

I didn’t know how short our time window would be to enter the cavern. When the spirit of Trophonius said “first light,” did he mean nautical twilight? Dawn? The moment when the sun chariot’s headlights were first visible, or when the chariot was high enough in the sky that you could actually read my bumper stickers? Whatever the case, we had to hurry.

Meg adjusted her glasses. She started to edge sideways for an unobstructed view around the bushes when one of the creatures lifted its head just enough for me to glimpse its horns.

I stifled a scream. I grabbed Meg’s wrist and pulled her back into the cover of the hackberries.

Normally, that might have provoked a bite from her, but I was willing to risk it. It was a little too early in the morning to watch my young friend get killed.

“Stay very still,” I whispered. “Those are yales.”

She blinked one eye, then the other, as if my warning was slowly making its way from her left brain to her right. “Yales? Isn’t that a university?”

“Yes,” I murmured. “And one of Yale University’s symbols is the yale, but that’s not important. These monsters…” I swallowed down the aluminum taste of fear. “The Romans knew them as centicores. They are absolutely deadly. They’re also attracted to sudden movements and loud noises. So shh.”

In fact, even as a god, I had never been this close to yales before. They were fierce, proud animals, highly territorial and aggressive. I remembered catching a glimpse of them in my vision of Commodus’s throne room, but the beasts were so rare I’d half convinced myself they were some other manner of monster. Also, I could not imagine that even Commodus would be crazy enough to keep yales in such proximity to humans.

They looked more like giant yaks than cows. Shaggy brown fur with yellow spots covered their bodies, while the fur on their heads was solid yellow. Horselike manes trailed down their necks. Their fluffy tails were as long as my arm, and their large amber eyes…Oh, dear. The way I’m describing them, they sound almost cute. Let me assure you, they were not.

The yales’ most prominent features were their horns—two glistening white spears of ridged bone, absurdly long for the creature’s head. I had seen those horns in action before. Eons ago, during Dionysus’s eastern campaign, the wine god had unleashed a herd of yales into the ranks of an Indian army five thousand strong. I remembered the screams of those warriors.

“What do we do?” Meg whispered. “Kill them? They’re kind of pretty.”

“The Spartan warriors were kind of pretty, too, until they skewered you. No, we can’t kill yales.”

“Okay, good.” A long pause, then Meg’s natural rebellious streak kicked in. “Why not? Is their fur invulnerable to my swords? I hate that.”

“No, Meg, I don’t think so. The reason we can’t kill these creatures is that yales are on the endangered-monster list.”

“You’re making that up.”

“Why would I make up such a thing?” I had to remind myself to keep my voice down. “Artemis is very careful about monitoring the situation. When monsters start to fade from mortals’ collective memory, they regenerate less and less often from Tartarus. We have to let them breed and repopulate!”

Meg looked dubious. “Uh-huh.”

“Oh, come on. Surely you heard about that proposed temple of Poseidon in Sicily? It had to be relocated simply because the land was found to be the nesting area of a red-bellied hydra.”

Meg’s blank stare suggested she hadn’t heard about that, even though it had been headline news just a few thousand years ago.

“At any rate,” I persisted, “yales are much rarer than red-bellied hydras. I don’t know where Commodus found these, but if we killed them, all the gods would curse us, starting with my sister.”

Meg gazed again at the shaggy animals grazing peacefully in the meadow. “Aren’t you already cursed by the River Styx or whatever?”

“That’s not the point.”

“Then what do we do?”

The wind shifted. Suddenly, I remembered another detail about yales. They had an excellent sense of smell.

The pair simultaneously lifted their heads and turned their lovely amber eyes in our direction. The bull yale bellowed—a sound like a foghorn gargling mouthwash. Then both monsters charged.

I remembered more interesting facts about yales. (Had I not been about to die, I could have narrated a documentary.) For such large animals, their speed was impressive.

And those horns! As yales attacked, their horns swiveled like insect antennae—or, perhaps more accurately, the lances of medieval knights, who had been so fond of putting these creatures on their heraldic shields. The horns also spun, their sharp ridges corkscrewing, all the better to pierce our bodies.

I wished I could take a video of these majestic animals. I would’ve gotten millions of likes on GodTube! But if you have ever been charged by two woolly spotted yaks dual-wielding lances on their heads, you understand that camera work in such circumstances is difficult.

Meg tackled me, pushing me out of the yales’ path as they rushed through the hackberries. The bull’s left horn grazed my calf, slicing through my jeans. (My jeans were having a bad day.)

“Trees!” Meg yelled.

She grabbed my hand and pulled me toward the nearest stand of oaks. Fortunately, the yales were not as fast turning as they were charging. They galloped in a wide arc as Meg and I took cover.

“They’re not so pretty now,” Meg noted. “You sure we can’t kill them?”

“No!” I ran through my limited repertoire of skills. I could sing and play the ukulele, but yales were notoriously tone-deaf. My bow and arrow would do me no good. I could try to simply wound the animals, but with my luck, I’d end up accidentally killing them. I was fresh out of ammonia syringes, brick walls, elephants, and bursts of godly strength. That left only my natural charisma, which I didn’t think the yales would appreciate.

The animals slowed as they approached. Probably, they were confused about how to kill us through the trees. Yales were aggressive, but they weren’t hunters. They didn’t use fancy maneuvers to corner and defeat prey. If somebody got in their territory, they just charged. The trespassers died or fled. Problem solved. They weren’t accustomed to intruders who played keep-away.

We edged around the oaks, doing our best to stay opposite the beasts.

“Nice yales,” I sang. “Excellent yales.”

The yales did not seem impressed.

As we shifted perspective, I spotted something about thirty yards beyond the animals: a cluster of washing-machine-size boulders in the tall grass. Nothing terribly dramatic, but my keen ears picked up the sound of trickling water.

I pointed out the rocks to Meg. “The cave entrance must be there.”

She wrinkled her nose. “So do we run for it and jump in?”

“No!” I yelped. “There should be two streams. We have to stop and drink from them. Then the cave itself…I doubt it will be an easy descent. We’ll need time to find a safe way down. If we just jump in, we might die.”

“These harvards aren’t going to give us time.”

“Yales,” I corrected.

“Same difference,” she said, totally stealing my line. “How much do you think those things weigh?”

“A lot.”

She seemed to run that through her mental calculator. “Okay. Get ready.”

“For what?”

“No spoilers.”

“I hate you.”

Meg thrust out her hands. All around the yales, the grass went into overdrive, braiding itself into thick green ropes that wrapped around the beasts’ legs. The creatures thrashed and bellowed like gargling foghorns, but the grass continued to grow, climbing across their flanks, entangling their massive bodies.

“Go,” Meg said.

I ran.

Thirty yards had never seemed so far.

Halfway to the rocks, I glanced back. Meg was stumbling, her face glistening with sweat. It must have been taking all her strength to keep the yales entangled. The beasts strained and spun their horns, slashing at the grass, pulling against the sod with all their might.

I reached the pile of rocks.

As I’d suspected, from side-by-side fissures in the face of one boulder, twin springs gurgled, as if Poseidon had come by and cracked the stone with his trident: I want hot water here, and cold water here. One spring bubbled diluted white, the color of nonfat milk. The other was as black as squid ink. They ran together in a mossy streak before splattering against the muddy ground.

Beyond the springs, a crevasse zigzagged between the largest boulders—a ten-foot-wide wound in the earth, leaving no doubt as to the presence of the cavern system below. At the lip of the chasm, a coil of rope was tied to an iron piton.

Meg staggered toward me. “Hurry,” she gasped. “Jump in.”

Behind her, the yales were slowly ripping through their grassy bonds.

“We have to drink,” I told her. “Mnemosyne, the Spring of Memory, is black. Lethe, the Spring of Forgetfulness, is white. If we drink both at the same time, they should counteract each other and prepare our minds—”

“Don’t care.” Meg’s face was now as white as the waters of Lethe. “You go.”

“But you have to come with me! The Oracle said so! Besides, you won’t be in any shape to defend yourself.”

“Fine,” she groaned. “Drink!”

I cupped one hand in the water of Mnemosyne, the other hand in the water of Lethe. I gulped them down simultaneously. They had no taste—just intense, numbing cold, the sort that hurts so badly you don’t feel the pain until much later.

My brain began to swivel and corkscrew like a yale horn. My feet felt like helium balloons. Meg struggled with the rope, trying to wrap it around my waist. For some reason, I found this hysterical.

“Your turn,” I giggled. “Drinkie, drinkie!”

Meg scowled. “And lose my wits? Nuh-uh.”

“Silly willy! If you don’t prepare yourself for the Oracle—”

In the meadow, the yales ripped themselves free, peeling off several square yards of turf from the ground.

“No time!” Meg lunged forward, tackling me around the waist. Like the good friend she was, she sent me tumbling over the ledge and into the black void below.
