A true architect of genocide, Krall is a fanatically loyal and brutal officer of the Imperial Army, as well as a Lord within the Order of the Dark Hand. He can be somewhat overbearing and meticulous, considering others as for the most part inferior in ability. Usually civil to those who converse with him, he is however known to consider the majority of his relationships as temporary. With a somewhat biting conversational attitude combined with a fascination of philosophy, he is prone to engage in lengthy arguments about even the slightest of details.
