Tossing an idea out there - depending upon how long each of us has been at the Oasis, our characters may have gotten to know each other. Relationships may have formed, be it friendship, casual acquaintanceship, drinking buddies, sparring partners, etc. Teaching and/or learning new skills from NPCs or each other maybe. 

Looking at character histories and their locations during the war, some of them might even have relationships prior to coming to Oasis. Any thoughts?

The Knight might have known some of the guard characters, but this would have been before his transformation. As it is now, there's no way they would be able to recognize him, and even if he does recognize them somehow--he'd have to have been more than just passingly familiar with them--he can't communicate it. Still, for other characters, this might be an interesting way to get some investment into the RP early on.
