"What? Cultists?? But... oh bugger...." Ozzie said, before his face showed a dawning revealation, "My future, your past. Damn it, I hate it when this happens."
He walked over to get a better look at the locks as he continued,
"Look, say nothing else about whatever happened with the cultists. I don't know what happened but I also can't know what happened. Just so you know, I haven't got a clue who you are but if you know me enough to be shouting my name for help, then I guess I can trust you. Oh, and you should probably know, apart from you, me and two other guys back there, everyone has vanished, clerics included."
He paused for a moment as he inspected the locks more before saying,
"Hmm, good locks. Strong, sturdy, and I don't have a way to unlock them without keys. I don't suppose you know where they are?"
