Jaghatai Khan (pronounced Jagg-a-tie KAAN), also known as “The Great Khan,” “the Khagan” and “the Warhawk,” was the primarch of the V Legion of Space Marines, the White Scars, who led them through the years of the Great Crusade and the Horus Heresy. Jaghatai fought alongside his White Scars for another 70 standard years following the end of the Heresy, eventually disappearing in 084.M31 into a region of space known as the Maelstrom, a large Warp rift in the Ultima Segmentum that is a smaller counterpart of the Eye of Terror. Jaghatai is believed to have been in pursuit of the Drukhari who had savaged his homeworld of Chogoris following the Battle of Corusil V with his 1st Brotherhood when he went through a Warp Gate into the Drukhari portion of the Webway. Jaghatai had been in pursuit of a mighty Drukhari lord, likely the Archon of the Drukhari Kabal that had attacked Corusil V and perhaps even Chogoris itself.
