He will have no offspring for no female would join with him for once he was scarred he was considered "unfit". The Tornian Empire has been dying ever since the great infection caused the birth of females to become a rarity. Since then they have been searching the known universes for compatible females. The Emperor's discovery of a compatible female on a slave ship changed that. He'd ordered Grim to find his Empress's home world so more "unprotected" females could be obtained, knowing Grim would never be allowed to Join with one.
