Sorry for the lateness! My cat developed Urinary Tract Infection, which means I now spend most of the day making sure she doesn't pee on anything I particularly like. But I'm working on a post now!
I will list out everything clearly at the first post. :) But here's the answer - in the 1st post, everyone will get to the cafeteria and eat while waiting for Warden's announcement. Also, you've been instructed to get to a long table in the middle of the room where a row of pokeball's there with names on top, waiting to be chosen. You then get your starter.
