Son of Diago Rensin, Sir Rensin inherited his father's knighthood in a part of the the Old Kingdom called Cronberg. He moved to the West when Sir Gregory Grimwar moved there, but did not go to West End. Instead, he led a band of Knights who intended to conquer West End. Not a wholly unlikable man, he still intended to conquer West End by force and still might have if the Company of the Red Spear was unable to convince Sir Gregory Grimwar to take action in one way or another.
