How about "Brigadier"
It has a military connotation to it, but without "general" attached, it also has that old D&D thesaurus inspired naming-- using obscure words and bringing them into common usage. Like when a Cavalier got to a certain level and became a Chevilier, etc. Where it not for D&D, most of us would only consider Constitution to be a written document outlining the laws of a nation.
So go ahead, D&D-- expand our vocabularies once again! Dig into that thesaurus and find an old way to give us a new concept!
