Dominiac is a character from Final Fantasy XIV: Heavensward.
Dominiac seeks to help Ser Aymeric reform Ishgard but due to lacking noble blood, Dominiac found himself unable to achieve that goal unless acknowledged for a great achievement. Dominiac goes to the Convictory but things do not go as expected becoming a commanding officer. With information from the Warrior of Light, Dominiac makes a plan to use weak dragon bodies to lure larger dragons until they can gradually defeat a powerful dragon. Dominiac leaves the execution of the plan to a new recruit in the Convictory, Saintrelmaux while Warrior of Light assists him. Dominiac remains the Convictory following the progress of the mission.
The body of a wyvern killed by the Warrior of Light is stolen by a nobleman, willing to give in to the nobleman's demands to return the body, Dominiac sends Saintrelmaux in command of a troop to negotiate. The deal ends with a dragon being lured to the body and killing the nobleman, and later the Warrior of Light defeating the dragon. Once all is over, Dominiac informs Ishgard about the events and decides to change the Convictory to the home of elite fighters.
Dominiac is a NPC available for Triple Triad matches added in patch 3.0. He is located at Coerthas Western Highlands (16.6, 22.6). To challenge him the player needs to complete the sidequest A War without End.
