Taff is a servant in Mercystar's palace in Hallandren on Nalthis.
Taff is in a hallway with three other servants when they are attacked by Vasher as he infiltrates the palace. Taff is immediately tied up with an Awakened rope. Rariv and another servant run for help; Lolan becomes distracted by Nightblood and is knocked unconscious by Vasher. When help arrives, the rope binding Taff is no longer Awakened, but he has been stabbed and killed. After interviewing the witnesses, Lightsong deduces that the initial assailant (Vasher) was not the murderer. The killer was Denth, who was tailing Vasher. Taff was presumably killed because he was the only person who would have been able to identify Denth.
