Not to knock it, but perhaps we can think of a more interesting title for our player characters than "Custodians?" I understand what's intended, but it seems like something that would be [url=http://en.wikipedia.org/wiki/The_Librarian_(franchise)]played for laughs[/url]. I'm sure we can come up with something that's just as fitting and a bit cooler sounding without becoming cliche. Perhaps "Wardens" or "Sentinels." If we really want to mix it up (and add a bit of cheese to this) we can have it be an overlong acronym. Off the top of my head, MARAUDERS (Mechanized Assault, uh, Reconnaissance... something, something...)
