'Sup mortals!
I'm Percy Jackson. (Which you should know by now, with my awesome books and all) son of lord Poseidon, so tremble in fear. (Don't worry, he's not as scary as you think.) 
Annabeth forced me to join. Go talk to her. And while you're at it, Leo's here too. (For better or worse)
@AnnabethC_700
@Leo_BadBoySupreme
And Piper
@PiperMcLean50
More'll join. Almost positive about it.
So... yeah. Think I got it all down. I'm a half-blood. I was forced into joining this place and... well yeah. That's it.
