An In the time of the [[Great Crusade]], Ignis was an adept of the '''[[Order of Ruin]]''', Ignis . He specialized in the statistical and tactical acumen of war, using a combination of numerology and staggering mathematical acumen to be able to analyze enormous quantities of battlefield data to predict enemy actions and perform incredibly precise battlefield actions. During the [[Horus Heresy]], Ignis joined with [[Ahriman]]'s party to reclaim the shards of [[Magnus]]. During the battle on [[Kamiti Sona]] Ignis commanded the warship ''Khemet'' but was out-maneuvered by a [[Knights-Errant]] stealth corvette commanded by [[Antaka Cyvaan]]. Ignis only survived by projecting himself out of the ''Khemet'' and into a nearby [[Reaver Titan]].{{Fn|1}} Ignis next appeared during the [[Solar War]], aiding Ahriman in initiating his ritual on [[The Comet]] which allowed for traitor forces to appear directly over [[Luna]].{{Fn|3}} During the [[Siege of Terra]] he helped plan the attack on the [[Colossi Gate]].{{Fn|4}}
After the Heresy, Ignis joined Ahriman's [[Prodigal Sons]].
