The seven...at HOGWARTS?!

Reality or a vision...

Percy's POV

"Umm, so that's it? The usual dangers, blah, blah, blah?"

" Yes that is it. You will now be transported to Olympus so that Hecate blesses you with magic for the school year. Then you will have to pack and go shop for some things in Diagon Alley"

"Funny name" said Annabeth.

"So about when are we gonna go?" asked Frank. 

"Right about...now" 

There was a flash of white, and I blinked.

When I next opened my eyes, we were in the throne room, where the gods, as always, were shouting about something.

Finally, Poseidon noticed me and the others and said, " Percy, demigods, welcome"

"Yes, welcome, am I right to suppose that Chiron has already explained everything?" boomed Zeus.

"Yeah, he did" said Jason.

"Very well. HECATE" Zeus called.

There was another flash, and as it faded away, Hecate took its place, and she said, "Good. All of you must now close your eyes and imagine yourself as a powerful being. You will feel as if you float, and black out. Then you will be blessed by magic"

Ok then...

I imagined myself as something powerful...

More powerful than the sea...

power flowing through my veins...

I felt myself lift off the ground, and then it went black.

Like, for a second.

It seemed like no time had passed when I opened my eyes.

However, when I came to, I was laying in my bed in the Poseidon Cabin.

I climbed out of my bed, and was going to open the door, when the bathroom creaked open and a tall towering man came out.

He had a sickly pale face, glaring red snake-like eyes, and slits for a nose.

I wanted to scream, but the sound was stuck in my throat. Then the man whispered some weird sounding words: 

"Avada...Kedavra"

A flash of green light, and pain.
