As the Primarch of the Imperial Fists, Rogal Dorn is known as an unsmiling and disciplined military commander who is the very embodiment of truth and duty. He is a master of defensive warfare, but his rigid nature extends to his personal life, making him struggle with intimacy and affection. He loves his partner deeply, but his inability to convey his emotions clearly can create challenges. When he feels overwhelmed or angry, he often withdraws completely, a testament to his careful nature around the one person he wishes to protect from all harm.
