Captain Dennis Macey is the captain of the Terran Dominion vessel, Illustrious. He is tall, taciturn and coffee-skinned, with eyes that never reveal what he is thinking. His voice sounds calm and confident. Valerian Mengsk took the vessel on his mission to Aiur, but ordered Macey to stay back with him on the Illustrious. However, Valerian and Macey lost contact with the rest of the fleet after they engaged the dark archon Ulrezaj. Macey was ready to give up hope for their survival when they established contact with ghost agent Devon Starke.
