Mullen is a ruddy-faced Knorth Kendar whose name Torisen forgets in To Ride a Rathorn, breaking his bond with the man. Mullen goes missing, and even though the Gothregor Herbalist Kells reminds Torisen of the man's name, this doesn't remake the bond.
Torisen's steward Rowan finds Mullen in the death banner hall of the keep; he has been slowly killing himself in there with a white-hilted knife, hoping hopelessly that some remnant of the bond remained and that Torisen would feel his pain and find him, as a Lord will find his wounded men on the field after a battle and give the mortally wounded the release and honorable death of the white knife. It doesn't work; Torisen feels nothing and is unaware of the man's plight. He's still alive when they find him, barely, holding onto life only in the hope of being recognized again; Torisen tells him, "Mullen. Welcome home." and he dies, happy.
- ↑ To Ride a Rathorn, "Chapter VIII: A Forgotten Name", II — "But he thought that he had at least rescued the missing Kendar—a middle-aged Danior yondri, he now remembered, One-Who-Had-Returned. When the man had knelt before him, he had seen the three wavy scar lines of the Knorth sigil branded on the back of the man's neck."
- ↑ To Ride a Rathorn, "Chapter 3: Wine, Women, and Wolvers", III — "A Kendar offered him a cup of mulled cider. Although his stomach revolted at the thought, he accepted it and started to thank the man, but couldn't recall his name. That had never happened before, not with someone bound to him. The other's smile faltered and his ruddy face paled in blotches as he felt the bond to his lord weaken."
- ↑ To Ride a Rathorn, "Chapter VIII: A Forgotten Name", I — "The herbalist turned to straightened his work area. 'My lord…' he said over his shoulder. 'Yes?' 'The missing Kendar is named Mullen.' "
- ↑ To Ride a Rathorn, "Chapter VIII: A Forgotten Name", VI — "Below that, the broad chest and gnarled arms seemed to hang in dark, clotted tatters, as if he had started cutting the wavy lines of the rathorn sigil into his clothes and gone on to the skin beneath, […] The man was still breathing, but just barely. His eyes half opened like those of a tired child reluctant to wake. Then he saw who bent over him and smiled. 'My lord.' Torisen gripped the Kendar's worn hand. 'Mullen. Welcome home.' The smile remained, but the eyes lost their focus and no breath returned."
- ↑ Bound in Blood, "Epilogue", II — " 'Blood binds. Fire loosens. Go in peace.' Of those aware, a dozen were left. Among them were Kinzi and, of course, Mullen."
