There has been speculation that Norathar may be the "mutual friend" that Kragar claims introduced him to Mario. The argument goes that Norathar, having been forced out of the House of Dragon, would have sought to learn a new trade in the House of Jhereg. Having determined that her skills and temperment suited the role of a Jhereg assassin, she would have sought out the best known assassin, i.e. Mario, to perfect her skills in this vocation.
