Hugo is the Emperor of Mor Ardain. His brother was unable to become a Driver, so Hugo accordingly became the Driver of both Brighid and Aegaeon. His brother rules in his absence and has given the Special Inquisitor instructions to retrieve his Core Crystals should he fall in battle. Hugo and Addam have an undisclosed history together and were once very good friends. Both Hugo and Addam share a distaste for ruling over others.
