Captain of the Oathkeeper
Belmorn is a middle-aged human who owns and captains the Oathkeeper, a spelljammer that operates out of Sigil. He has demonstrated some arcane ability in piloting the Oathkeeper, but has not disclosed much about his own past or capabilities.
Belmorn treats his crew with fairness and respect, even those operating under indentured servitude, and has paid a bonus to the families of crewman that died protecting his ship.
Belmorn is a skilled astral scavenger, but whether or not he has further goals for the ship and its crew remains to be seen.
