Character from Malazan Book of the Fallen by Steven Erikson
Commander of the Crimson Guard, bound by a terrible Vow that grants immortality at a cost none of them fully understood when they swore it.
K'azz D'Avore led the Crimson Guard in their Vow against the Malazan Empire — an oath so powerful it granted the Avowed immortality and superhuman resilience. But the Vow's price is steep: it binds their souls, traps them in an endless war, and the longer it endures the more it warps them. K'azz carries the weight of this knowledge, knowing he led his people into an oath that may damn them. He is weary, dutiful, and haunted by responsibility.
Ageless face that could be thirty or three hundred, with dark hair and calm, steady eyes. Wears the crimson surcoat of the Guard's commander. Lean and fit, radiating quiet authority.
Also known as: K'azz D'Avore, K'azz, Commander K'azz
