After these events, Dukat continued serving as Supreme Legate of the Central Command. Dukat began pressing for and planning the invasion and occupation of Bajor as revenge for their succession from the Alliance and Ro Laren's treason. However, before the invasion could take place, Dukat was killed by his second in command, Damar, in full view of the entire Cardassian people, who was acting under the telepathic manipulation of one of his Vulcan slaves. Damar ultimately succeeded him as Supreme Legate. (Mirror Universe novel: Rise Like Lions)
