Five carries something of the dead on him. Based on past occurrences, and the increasing paranoia he's suffered over the past two years, I'd believe it's from Anurr rather than the dead body parts we, and he, are otherwise collecting. Some sort of favour, perhaps? Not sure if it's the only one, I'd suggest investigating with Xiao Xingchen and Xie Lian for their past relationship with Anurr's followers in Sa-Hareth, if that was in any way meaningful at that time or rebirthed when he came into his full powers in Taravast.
