A faction within the Pit (to be trusted?)
An organization apparently in possession of several military fortifications within the Pit, seemingly with a vested interest in the public good, or at least lawful order. Lt. Graves wears their symbol on his armor: the Shielded Coat of Arms of King Elric, slashed in half.
Little is known of their methods, their current aims, their degree of control over the Pit, their finances, their enemies, their allies, or their ideals. Time will tell, provided that the party survives long enough to learn.
