Following the self-imposed exile of Chapter Master Arkash Hakkon at the start of the Badab War, the position of High Executioner remained vacant and Lord Speaker of the Dead Thulsa Kane held command of the chapter. At the conclusion of the Badab War, the Executioners were placed on a one-hundred year penitent crusade.
Having fulfilled their oath to the Astral Claws and received their punishment for their role in the rebellion, Thulsa Kane declared that the time had come for a new High Executioner. By tradition, the position was open to any company Captain and would be determined by combat. The Captain of the second company, Donalt Arkhan, was the first to declare his claim, and he was quickly followed by the eighth company Captain, Hamon Thoth-Kapara, immediately declared their intention to fight for the title. Next to speak was Tytos Solomon, Captain of the fourth company. After the grim declaration by the black-cloaked Astartes, no further claimants came forward.
