The only head of the Obsidian Order who lived long enough to retire, Tain was a stubborn, wily survivor who epitomized the efficiently ruthless agency and thrived on the labyrinthine intrigue of his people -- a man the regular military's Central Command dared not challenge.Hoping for a comeback from his retirement in 2368 to the Arawath colony and Unefra III, Tain engineered a disastrous joint attack on the Dominion and the Founders' homeworld three years later. The Obsidian Order alligned with the Romulan Tal'Shiar in a plot doomed early on by unknown, shapeshifter infiltrators.Tain's housekeeper and confidant for over 30 years was Mila, who oversaw him as an older man until the Dominion invasion.
