Bult was an older Wickan warrior who accompanied Coltaine to Seven Cities before the onset of the Whirlwind rebellion. Coltaine sometimes jokingly referred to the veteran commander as "uncle", although the veracity of this claim was left unclear. He was described as having a wide flat face which seemed to fold in on itself diagonally due to a scar which ran from the right jawline to the left brow. He also had gnarled, bandy legs and jagged teeth. Bult claimed in jest that the loss of his youthful beauty had limited him to one blind wife.
