I Meet My Undersea Immortal Relatives

I hate dream visions.

Dream visions are visions omens and other mystical stuff that can show the past, the present, and at times the future and it almost never good.

I dreamed I was in a dark palace at the top of a mountain. Unfortunately, I recognized it: the palace of the Titans on top of Mount Othrys, otherwise known as Mount Tamalpais, in California. The main pavilion was open to the night, ringed with black Greek columns and statues of the Titans. Torchlight glowed against the black marble floor. In the center of the room, an armored giant struggled under the weight of a swirling funnel cloud—Atlas, holding up the sky.

Two other giant men stood nearby over a bronze brazier, studying images in the flames, which I recognized as two of the four of Kronos' brothers that helped him take down their father.

"Quite an explosion one said. He wore black armor studded with silver dots like a starry sky. His face was covered in a war helm with ram's horns curling on either side. My guess this was Krios, Titan of the south.

"It doesn't matter," Krios' brother said. This Titan was dressed in gold robes, with golden eyes like Kronos. His entire body glowed. He reminded me of Apollo, God of the Sun, except the Titan's light was harsher, and his expression was crueler. This had to be Hyperion: Titan of the east and Lord of Light. "The gods have answered the challenge. Soon they will be destroyed."

The images in the fire were hard to make out: storm, building crumbling, mortals screaming in terror.

"I will go east to marshal our forces," Hyperion said. "Krios, you shall remain and guard Mount Othrys."

Krios grunted. "I always get the stupid jobs. Lord of the South. Lord f Constellations. Now I get to babysit Atlas while you have all the fun."

Under the whirlwind of clouds, Atlas bellowed in agony. "Let me out! I am your greatest warrior. Take my burden so I may fight!"

"Quiet!" Hyperion roared. "You had your chance, Atlas. You failed. Kronos likes you just where you are. As for you Krios, do your duty."

"And if you need more warriors?" Krios asked. "Our treacherous nephew in the tuxedo will not do you much good in a fight."

Hyperion laughed. "Don't worry about him. Besides, the gods can barely handle our first little challenge. They have no idea how many others we have in store. Mark my words, in a few days' time, Olympus will be in ruins, and we will meet here again to celebrate the dawn of the Sixth Age!"

Hyperion erupted into the flames and disappeared.

"Oh, sure," Krios grumbled. "He get to erupt into flames. I get to wear these stupid ram horns."

The scene shifted. Now I was outside the pavilion, hiding in the shadows of a Greek column. A boy stood next to me, eavesdropping on the Titans. He had dark silky hair, pale skin, and dark clothes—my friend Nico di Angelo, the son of Hades.

He looked straight at me, his expression grim. "You see, Percy?" he whispered. "You're running out of time. Do you really think you can beat them without my plan?"

His words washed over me as cold as the ocean floor, and my dreams went black.

"Percy?" a deep voice said.

My head felt like it had been microwaved in aluminum foil. I open my eyes and saw a large shadowy figure looming over me.

"Beckendorf?" I asked.

"No, brother."

My eyes refocused. I was looking at a Cyclops—a misshapen face, ratty brown hair, and one big brown eye full of concern. "Tyson?"

My brother broke into a toothy grin. "Yay! Your brain works!"

I wasn't so sure. My body felt weightless and cold. My voice sounded wrong. I could hear Tyson, but it was more like I was hearing vibrations inside my skull, not the regular sounds.

I sat up, and a gossamer sheet floated away. I was on a bed made of silky woven kelp, in a room paneled with abalone shell. Glowing pearls the size of basketballs floated around the ceiling, providing light. I was under water.

Now, being the son of Poseidon and all, I was okay with this. I can breath underwater just fine, and my clothes don't get wet unless I want them to. But it was still a bit of a shock when a hammerhead shark drifted through the bedroom window, regarded me, and then swim calmly out the opposite side of the room.

"Where—"

"Daddy's palace," Tyson said.

Under different circumstances, I would've been excited. I've never visit my dad Poseidon's realm, and I'd been dreaming about this since I was seven. But my head hurts. My shirt was still speckled with burn marks from the explosion. My arms and legs looked fine, but that could just because the ocean healed me. However, I still felt like I'd been trampled by a Laistrygonian soccer team in cleats.

"How long—"

"We found you last night," Tyson said, "sinking through the water. You also reaked worse than Polyphemus."

I laughed as I explained to Tyson about Beckendorf and mine experiment with masking demigod scent with the smell of dead carcasses of a Myrmekes hill. Tyson grinned when I told him it worked up until we ran into a giant crab.

"So did The Princess Andromeda—?"

"Went ka-boom," Tyson confirmed.

I smiled when I heard that. "Then all is left is to see if Beckendorf and Mrs. O'Leary made it to camp safely."

But then I thought about my dream: the Titans discussing the explosion as if it didn't matter, Nico di Angelo warning me that I would never beat Kronos without following his plan—a dangerous idea I'd been avoiding for more than a year.

A distant blast shook the room. Green light blazed outside, turning the whole sea as bright as noon.

"What was that?" I asked.

Tyson looked worried. "Daddy will explain. Come, he is blowing up monsters."

The palace might have been the most amazing place I'd ever see if it hadn't been in the process of getting destroyed. We swam to the end of a long hallway and shot upward on a geyser. As we rose over the rooftops I caught my breath—well, if you can catch your breath underwater.

The palace was as big as the city on Mount Olympus, with wide courtyards, and columned pavilions. The gardens were sculpted with coral colonies and glowing sea plants. Twenty or thirty buildings were made of abalone, white but gleaming with rainbow colors. Fish and octopi darted in and out of the windows. The paths were lined with glowing pearls like Christmas lights.

The main courtyard was filled with warriors—merman with fish tails from the waist down and human bodies from the waist up, except their skin was blue, which I'd never known before. Some were tending the wounded. Some were sharpening spears and swords. One passed us, swimming in a hurry. His eyes were bright green, like that stuff they put in glo-sticks, and his teeth were shark teeth.

Outside the main courtyard stood large fortifications—towers, walls, and antisiege weapons—but most of these had been smashed to ruins. Others were blazing with strange green light that I knew well—Greek fire, which can burn even underwater.

Beyond this, the sea floor stretched into gloom. I could see battles raging—flashing of energy, explosions, and glint of armies clashing. A regular human would've been crushed by the pressure and frozen by the cold. Even my heat-sensitive eyes couldn't make out exactly what was going on.

At the edge of the palace complex, a temple with a red coral roof exploded, sending fire and debris streaming in slow motion across the farthest gardens. Out of the darkness above, an enormous form appeared—a squid larger than any skyscraper. It was surrounded by mermen trying to attack it. The squid descended on the palace, swatted its tentacles, smashing whole columns of warriors. Then a brilliant arc of blue light shot from the rooftop of one of the tallest buildings.

The light hit the giant squid, and the monster dissolved like food coloring in water.

"Daddy," Tyson said, pointing where the light had come from.

I couldn't help but be amazed. I knew my dad was powerful, being one of the big three, but I never thought he could do that.

"Have you been in a fight?" I asked Tyson, "Like bashing heads and making thing explode?"

Tyson pouted, and I knew the answer before he replied. "I have been… fixing weapons," he mumbled. "Come. Let's go find Daddy."

My dad, Poseidon seemed to have aged forty year since I last saw him which is saying something since he's immortal.

We arrived at a temple which had a big open deck for a roof and was set up like a command center. A mosaic on the floor showed an exact map of the palace grounds and the surrounding ocean, but the mosaic moved. Colored stone tiles representing different armies and sea monsters shifted around as forces change positions. Buildings that collapsed in real life also collapsed in the picture.

Standing around the mosaic, grimly studying the battle, was a strange assortment of warriors. Only two of them I recognize from descriptions of the old stories. One was a merman with two fishtails instead of one, green skinned, armor studded with pearls, and black hair that was tied in a ponytail: my immortal half-brother Triton. The other was someone I had feared to meet: a lady in green armor with long black hair and strange little horn like crab claws: my immortal stepmother Amphitrite.

There was also a dolphin who was staring at the map intently. He looked like your average dolphin but I didn't question about it.

Standing next to them was an old man with flowing white beard and gray hair. His battle armor seemed to weigh him down. He had green eyes and smile wrinkles around his eyes, but he wasn't smiling. He was studying the map and leaning on a large metal staff.

"Delphin," the old man said. "Send Palaemon and his legion of sharks to the western front. We have to neutralize those leviathans."

The dolphin spoke in a chattering voice, but I could understand it in my mind: Yes, lord! It sped away.

At first I couldn't believe it, but it took me a while to realize who it was, "Dad?"

The old man looked up. I recognized the twinkle in his e yes, but his face… well I think I already covered that.

"Hello, Percy."

"What—what—" I didn't know how to finish my question without offending my dad.

Luckily my dad knew what I wanted to ask. "Percy, excuse my appearance. The war been hard on me. My realm is in a grim state."

I remembered how Pan looked when he disappeared: an ancient Satyr that was barely clinging to life. Back then I thought it was because he was waiting for death, but now I realized it was more about what he told my friends and me: about how his realm disappearing.

"It's okay, Percy. I should introduce you—I'm afraid you missed my lieutenant Delphin, God of Delphins. This is my, er, wife, Amphitrite. My dear—"

Amphitrite stared at me coldly, but I bowed in respect to her either way, "It's an honor to meet you."

This made Amphitrite smiled slightly but still held her cold stare. "The boy has better manners than I thought. If you excuse me, my lord. I am needed in the battle."

She swam away. I guess I don't blame her. Like Hades and Zeus, my dad hasn't exactly been loyal to his marriage, as he had children with mortal women, other immortal beings, and at times Nature spirits. And I doubt Dad fathering me when he was supposed to be under oath of the River of Styx to have no more half-blood children helped either.

Poseidon cleared his throat. "Yes, well… and this is my—er—other son Triton."

"Your son and heir," Triton corrected as his double fishtails swished back and forth.

"It's nice to finally meet you, Triton," I said bowing to my half-brother, "I read so much about you."

Triton turned to me a little surprise. "Really?"

I guess it's unusual to find a child of Poseidon that takes up an interest in reading because Dad explained, "He's a bit of a book worm as long as the book is in ancient Greek."

Triton then smiled, but there was no friendliness in his eyes. "Then the honor is mine, Perseus. I hope you plan to stay and help."

"Well, that depends on our dad since I'm technically a guest in his realm," I responded.

Dad tried to held back a chuckle. Even Triton held back a smirk.

Then he turned to our dad, "I will see you to the front line, Father." Then Triton turned to me, "I hope you don't fail our father or Olympus, Perseus Jackson."

I figured he was talking about the prophecy, so naturally I responded, "I don't plan too."

Triton nodded in approval. He then turned and nodded politely to Tyson and shot off.

Dad sighed. He raised his staff, and it changed into his regular weapon—a huge three-pointed trident. The tips glowed with blue light, and the water around it boiled with energy.

Just then a huge sea serpent appeared above us and spiraled down toward the roof. It was bright orange with fanged mouth big enough to swallow the gymnasium.

Hardly looking up, dad pointed his trident at the beast and zapped it with blue energy. Ka-boom! The monster burst into a million goldfish which all swam off in terror.

"Forgive Amphitrite and Triton's behavior for not properly greeting you, Percy. They're anxious," Poseidon explained. "The battle against Oceanus is going poorly."

He pointed to the edge of the mosaic. With the butt of his trident he taped the image of a merman larger than the rest, with the horns of a bull. He appeared to be riding a chariot pulled by crawfish, and instead of a sword he wielded a live serpent.

"Oceanus—the Titan of the sea?" I asked, "Wasn't he neutral in the first Titan war?"

Poseidon nodded. "Kronos has convinced him to fight. This is… well, it's not a good sign. Oceanus would not commit unless he was sure he could pick the winning side. We have been at war almost a year now. My powers are taxed. And still he finds new forces to throw at me—sea monsters so ancient I had forgotten about them."

I heard an explosion in the distance. About half a mile away, a mountain of coral disintegrated under the weight of two giant creatures. One was a lobster. The other was a giant humanoid surrounded by a flurry of arms.

"Briares!" I said.

I was happy to see him, but he looked like he was fighting for his life. He was the last of his kind—a Hundred-Handed One. We'd saved him from Kronos' prison last summer, and he adopted the idea of seeing me as his brother. I knew he'd come to help Poseidon, but I hadn't heard of him since.

"He fights well," Poseidon said. "I wish we had an army like him, but he's the only one."

"What about your other immortal children?" I asked.

"I'm afraid I don't know," Poseidon said, "But enough with this. Tell of your mission. Did you see Kronos?"

I told him everything that happened.

"Kronos' army will be disarray. Many were destroyed. You and Beckendorf did well," Poseidon said.

"But we didn't destroy him, did we?"

"No," Poseidon admitted, "But you two bought our side some time. Not to mention you might have found the perfect monster repellant. According to what I heard, when you were sinking none of Oceanus' forces dared to mess with you because of your stench."

I smiled. "I can't take all the credit. I actually got the idea from my mom back when she was married to Smelly Gabe."

Dad's smile grew a little. "Sally was always very smart."

"Dad, I had a dream vision while I was unconscious." I told him about my dream vision of Hyperion and Krios. Dad frowned at my description.

"I'm sorry, Percy. I don't think I should be the one to tell you what your dream means," Dad said, "I suggest you tell Chiron when you return to camp."

"Are you sure you want me to return? Your realm is in great danger?" I asked.

A fireball launched into the sky from behind enemy line and landed on the outer corner of the yard and exploded, sending mermen tumbling thrugh water. Dad winced as if he'd just been stabbed.

"Dad!"

"I'm fine," he insisted. "Go back to camp and tell Chiron it is time."

"Time? Time for—" My eyes widened as realization hit me, "You mean the Great Prophecy?"

Dad nodded. "The entire prophecy."

"Dad…"

"Percy, you must go," dad insisted. "Your destiny lies in the mortal world, not here. You must also warn your friends at Camp. Kronos knew of your plans. You have a spy, and possibly a double agent—possibly one you're not aware about—considering your pet hellhound came to your rescue without being called on. We will hold here. We have no choice."

Tyson gripped my hand desperately. "I will miss you, brother!"

Watching us, our father seemed to age another ten years. "Tyson, you have work to do as well, my son. They need you in the armory."

Tyson pouted some more.

"I will go," he sniffled. He hugged me so hard he almost cracked my ribs. "Percy, be careful! Do not let monsters kill you dead!"

I nodded confidently but the big guy still sobbed and swam away toward the armory, where his cyclopes bretherin, both brothers and cousins, were fixing spears and swords.

"You should let him fight," I told dad. "He hates being stuck in the armory while his family fights for their lives."

Poseidon shook his head. "Percy, the hardest thing for a parent to do is to see their child off to battle, even an immortal parent. It's hard enough for me to send you into danger and I don't want to send Tyson off either."

"But you haven't seen Tyson during the Battle of the Labyrinth, I have," I responded. "Tyson already can fight just as good if not better than I could at his age."

Dad didn't respond as he looked down at the mosaic and his shoulders sagged. On the tiles, Oceanus was coming closer to the battle.

"Oceanus approaches," my father said. "I must meet him in battle."

I'd never been scared for a god before, but I didn't see how my dad could face this Titan and win.

"I will hold," Dad promised. "I will not give up my domain. Just tell me, Percy, do you still have the birthday gift I gave you last summer?"

"Yeah," I responded, "I have it with the rest of the sanddollars I've saved."

"Good! The time will come when you'll need them," dad said. "I hope to see you for your sixteenth birthday next week, so we can have a proper celebration."

He smiled, and for a moment I saw the old light in his eyes.

Then the entire sea grew dark in front of us, like an inky storm was rolling. Thunder crackled, which should've been impossible underwater. A huge icy presence was approaching. I sensed a wave of fear roll through the armies below us.

"I must assume my true godly form," dad said. "Go—and good luck, my son."

I nodded. "Good-bye, dad, and I wish you and the rest of my immortal family down here good luck."

The last thing I saw was my father smiling as I turned away. I willed the ocean currents to aid me. Water swirled around me and I shot toward the surface at speeds that would've caused any normal human to pop like a balloon—another added bonus of being the son of the sea god.

When I looked back, all I could see were flashes of green and blue as my farther fought the Titan, and the sea itself was torn apart by the two armies.
