The Olympian Chronicles (Crossover)

HOORAY! I finally got over my laziness and wrote another chapter! Sadly, this one's short. I feel like I want to leave every chapter on a cliffhanger of some sort. I really enjoy making references to incredibly popular stories, by the way. Some of you will see what I did there with this cliffhanger ;)

We rushed back to the library in a hurry. When we got to the door, it was locked. "Twi, why did you lock the door?" I panted.

"I..." Twilight couldn't even talk, "D- did- duh GAH. Hold... on."

I rolled my eyes. Back at camp, we had to do ten-mile sprints without stopping every morning. Chiron was relentless.

She calmed her breath and focused. Her horn began to glow a bright purple until it was so bright I couldn't see her. Then she disappeared.

"What just happened?" I asked Pinkie.

"Haha, silly," she said exuberantly, "she just teleported into the house. She'll be back in a minute, but in the meantime..."

She began bouncing up and down she walked toward the door and literally passed through it like it was nothing. "Uh... I gotta go," Rainbow said, laughing. Then she flew off, leaving a rainbow in her wake.

I stood there, dumbfounded as Pinkie opened the door from the inside. She giggled at my gawking. "Well, aren't you going to come in?" she asked innocently.

I decided that there was no point in arguing. I followed her bouncing around inside, and saw a pony I'd only seen once before. She was beautiful. Her coat was pale, like Fluttershy's, but more vibrant, somehow. Her hair was still blonde and curly, but it blended into her coat. Her eyes were the same stormy gray, and her cutie mark was a book. She studied me with that intelligent curiosity of hers before walking up to me suspiciously.

"Seaweed Brain, you in there?" she asked cautiously.

"Yep. How was your nap?"

She punched me in the arm, and then tackle-hugged me. "It was so BORING in there, P-" I cut her off.

"You can't use my real name," I whispered, "call me Trident."

She looked cross, but she agreed. "Listen, I need to tell you something. The reason I was in the coma for so long is because Ares was giving me a special dream message. He explained to me what was going to take place in this world."

Twilight frowned, "Okay. Do you want to explain to everypony here, or just Trident?"

Annabeth smiled, "You all should hear this. It's about your world."

"You see, in Ares's dream, I learned the near future. If the war comes, there will be storms everywhere. The earth will split in many places. The oceans will rise to take the throne. This world will finally see its apocalypse. Celestia and Luna have ruled Equestria for thousands of years, and this war would end that. When you find all seven demigods, the path to stopping the war will be clear."

Twilight was glaring at us, "anything else with that little ray of sunshine? We already knew the war would cause catastrophe."

I don't know why Twi was so apprehensive towards Annabeth, but I didn't have time to ask, because Annabeth dropped another bomb.

"Well, I was kinda avoiding this, but," she said, looking at the floor, "there is one person that didn't get transferred correctly. He remained in the human world, but it is absolutely necessary that we bring him here."

"Who?" I asked, puzzled.

"You don't know him, Trident. Apparently somepony named Rainbow Dash does."
