The backstage Initiate room had a pretty sweet set-up.
Calling it merely a room was a misnomer, considering the open-plan space had three distinct sections. There was an area for people to get their practice on, featuring what looked like a high tech gym and sparring arena, though why anyone would want to give away their powers right before a fight was beyond me.
In another of the sections were a suit of medical bays that looked as if they could be reconfigured for basically any body type, though there didn't seem to be any medical staff present to actually render aid to anyone. Considering how powerful medical technology was in this universe, though, I wouldn't have been surprised if it were all automated.
