Found near the beginning of the Cathedral of the Deep, waiting atop the stairs that lead to the outer yard.
Not a very dangerous enemy, although a bit resilient. He often throws knives at the player and uses his axe's "Warcry" skill. However, he can only perform one swing at a time, which leaves him open for counterattacks afterward.
The battle can become quite difficult if the Unkindled Fallen Knight was not dealt previously and is allowed to join the battle, though.
