Azhtar Manutec was a Sorcerer within the Thousand Sons Legion during the Horus Heresy, but was later exiled by his Primarch Magnus for aiding in the disastrous Rubric of Ahriman. He would grow in power over the next ten millennia, and in the closing years of M41, he took part in Ahriman's failed attempt to capture the Ynnari Eldar during the War in the Labyrinth.[1]
