By 2377, Damar was serving as the second-in-command of Skrain Dukat, the Supreme Legate of the Cardassian Union. That year, Dukat began pressing for and planning the invasion and occupation of Bajor as revenge for their succession from the Alliance and the treason of Intendant Ro Laren. However, before the invasion could take place, Damar killed him in full view of the entire Cardassian people as he was acting under the telepathic manipulation of one of his Vulcan slaves. Damar ultimately succeeded him as Supreme Legate. (ST - Mirror Universe novel: Rise Like Lions)
