Annabeth, Grover and Chiron screamed. Free falling to the ocean without a parachute can be dangerous (not to mention scary).

"Could you guys shut up?" I yelled. I need to concentrate to maintain our momentum and use my powers to lessen the impact of the water.

They didn't shut up. Instead, they screamed even louder. It's hard to concentrate when there are three screaming creatures holding you.

I concentrated even harder and when it comes to the impact, I squeezed Annabeth, Grover and Chiron tighter so they wouldn't be injured by the impact of the water.

Splash! Splosh!

I rose to the surface as fast as I could.

"Annabeth!" I shouted.

"Here," Annabeth said as she rose from the surface. Her hair was badly ruined by the water.

"Chiron!" I yelled.

No answer.

"Grover!" I yelled.

No answer. Just a cricket sound.

Huh? Cricket? In the middle of the ocean?

Whatever. I dove into the water and opened my eyes. All I could see were endless blue and Grover. Grover!

I reached for him and grabbed him and he punched me at the nose. I squeezed him tight and bring him to the surface.

"What was the punch for?" I asked Grover.

"I thought you were a sea-lizard. Sorry," He replied.

I ignored him and dove into the water. Where's that horse? I couldn't see him. Front, back, left and right. No sign. What about below? I looked down and saw Chiron struggling free from a seaweed that was wrapping itself around Chiron's waist. His face was panicked. Then, I saw that it wasn't a seaweed wrapping Chiron, it's...it's...a...a...tentacle of an octopus! A giant octopus. Large one. XXXXXXXXXXL. Enormous.

Chiron was being pulled to the bottom. I wanted to chase Chiron but I have to bring Annabeth and Grover to help me. That thing was a million times bigger than a Cerberus or a Hydra. Gianormous. I can't face the beast alone.

I swam to the surface in panic.

"Chiron's in trouble! I need you guys to help me," I said in a fast tone and pulled them into the water. I made an air bubble for us to breathe. I brought them deeper and deeper by the second and everything started to go darker. I saw the tentacle speeding towards a cave. A big cave underwater (cool. That would be a great place for tourist to visit). We followed the beast as fast as we could. Once we entered deeper into the cave, we saw an open surface above us. We swam to the surface and the air bubble popped.

Pop!

We climbed to the surface and saw a giant, rocky gate infront of us. There are two dragons breathing fire at the side of the gate.

Annabeth and Grover were soaked wet and I was bone dry.

"The carvings are similar to the early Germanic design but older than the 5'th century," Annabeth said.

"Could you be anymore weird? What are you talking about?" Grover muttered.

Annabeth ignored him and stepped closer to the rocky, rough wall. Starting to read the carved symbols on the wall.

"Why am I always being ignored? Even Juniper does that," Grover shrugged.

"Proto-Norse Runes. Let's see. Hmm..."World of Mist"," Annabeth explained and remained silent for a while and continued, "It's Niflheim, the realm of the dead. Chiron's this way,"

"You mean he is in the realm of the dead being dead?" I asked.

"I'm not sure if he's dead but he's in the realm of the dead," Annabeth said.

"Confusing and not understandable," Grover muttered to himself.

"How do we open this gate?" I asked.

"Look! There's a lever there. Maybe that's the key to get in" Annabeth said.

There was a lever at the far end of the gate. I pulled the lever but it was stuck and rusty. Annabeth helped me pull that thing but no use.

"Little help here?" I said to Grover.

"I'm ignoring you because you always ignore me. Ignorance is your best friend now. Not me," Grover sulked.

"Don't be an emo, Grover. You know we love you," Annabeth coaxed him and with that, he helped us pull the lever with all his might and the lever finally moved and the gate opened.

"G-job, G-man!" I praised him.

"What does 'G-job, G-man' mean?" Grover asked me puzzled.

I sighed and said, "Good job, Grover man! Duh,"

"Oh. I don't get it," Grover was confused.

"You should make an IQ test and see what's your score, Grover," I cheered him and Annabeth laughed.

Her laughter echoed through the hall infront of us and we realized we have to keep moving on before Chiron was turned into roasted horse with apple chutney. That would be delicious to eat.

"Get moving, Lara Croft," I said to Annabeth.

"Shut up, Nathan Drake," Annabeth replied.

"What's my nickname? You guys had yours" Grover said.

"Penny Pingleton," Annabeth suggested, almost cracking up.

"She's from the movie named 'Hairspray' right? I love her. I'll take it," Grover agreed.

Annabeth cracked up.

"Grover, Penny Pingleton is a girl," I said to Grover.

"Who cares?" Grover said.

We entered the hallway infront of us. I could hear water droplets dripping from the ceiling to the ground. It was a long hallway with stairs. After 5 minutes of climbing stairs, we finally reached another room. A big room. We were on a platform high above the ground. At the middle of the room was a...a...gianormous octopus.

"That's the thing that took Chiron!" I shouted.

"Shut up, Percy. That thing's going to kill us if it heard us!," Annabeth shouted even louder, "Uh-oh,"

It smashed it's tentacles at the ceiling and dozens of rocks fell from above. We dodged the rocks as best as we could but one hit me on the left foot, one hit Annabeth on the shoulder and two hit Grover at the head.

"That's a kraken. Definition: giant octopus. From the 'Pirates of the Carribean'," Annabeth explained.

"That beast is blind. But it's hearings are sharp. So does it's other senses," Grover said.

"How did you know?" I asked.

"I can talk to animals. You can't," Grover muttered.

"That's not an animal. That's a beast!" I yelled.

The Kraken smashed it's tentacle at the platform we were standing and the platform shook and water from the Kraken's tentacle sprayed onto my face.

The water was like acid. The water was cold but it's hot. My face almost scalded because of it. What kind of water is that?

"It's celtic blue liquid! It's highly dangerous. It may look like water but in the celtic underworld, that liquid shines in light blue colour. Get it off your body. It's like acid. It could kill you!" Annabeth warned.

I wiped the liquid off my whole body immeadiately after Annabeth said that.

"Maybe that's why I can't controll the water back in Thailand. It's celtic blue liquid," I realized.

"Maybe," Grover agreed, "But why didn't the water back in Thailand felt like acid? It felt like normal water to me,"

"Maybe it's because that celtic blue liquid is kept in that room for a long time. It's like, expired. But still contains the power of the liquid. Daedalus's file about norse mythology is useful after all," Annabeth said, "But I left it at camp! Darn it!"

Suddenly, we heard a scream.

"Percy, Annabeth, Grover, HELP!"
