Not much is known of Gor'Hal's early years other than he was born on the planet of Mon'Torkal and he has a twin brother called Fel'Hal. Both would be inducted into the Iron Warriors Legion soon after the compliance of Mon'Torkal and they would each pursue different paths within the Legion. Gor'Hal possessed an extremely high intellect, learning and mastering the arts of Techmarines and thrived in close combat using combat mauls and warhammers. He would also be one of the best students of grand strategy during his training and education. The Warsmith Tytos took a great interest in Gor'Hal and would take him under his wing once Gor'Hal's training and induction into the Legion was complete.
