Lucan

Lucan is a Breton necromancer and member of the Order of the Black Worm in the third and fourth eras. Born into a

noble house in High Rock, he was banished from his family after dabbling in necromancy. From there, he established contact with the Order of the Black Worm and became a favorite of Mannimarco, a age-old lich and leader of the Worm Cult.

Lucan became the Worm King's chief lieutenant and was sent to Cyrodiil in the final days of the Third Era to infiltrate the Mages Guild of Cyrodiil, the cult's biggest rival, in order to gather intel in preparation for an all out war against the guild. After earning the trust of the guild and joining their ranks, Lucan slowly worked his way to the top. In a carefully planned powerplay, Lucan managed to start the so called 'War of the Worm' prematurely and trick Mannimarco into revealing himself. From there, Lucan confronted him and killed him, taking his place and becoming Mannimarco, King of Worms himself (though only in title). Mannimarco would later be resurrected by Worm Cult dissidents, leading to yet another power struggle between the two necromancers.
