In 211 AC, Daemon defeated three sellsword companies, the Volantene army and a Dothraki khalasar, which led to the conquest of Volantis. After a few years of solidifying his control over the three cities, Daemon managed to attract even more opportunists from the west and managed to conquer Norvos and Qohor. From there, Daemon's armies and fleets took Myr and Lys. Starting from Tyrosh in 196 AC, where the Archon was the father of Daemon's wife Rohanne, Daemon and his army of followers from Westeros began their conquest. In return for his support, Daemon renounced his claim to the Iron Throne. As a parting gift, Daeron gifted three dragon eggs to Daemon.
Eager to rid himself of him, Daeron II approved of it and allowed for any and all men who wish to join him to do so.
While some of them preferred to make him king in Westeros, most saw the many opportunities such a new empire offered them. Daemon and Daeron disliked one another, but eventually Daemon settled the matter when he announced before his followers that he intended to forge an empire for himself - in Essos. His bastard son, Daemon Blackfyre was very popular with the people, who disliked his trueborn brother Daeron II and whispered that he should be king instead. In his last will and testament, Aegon IV Targaryen, legitimized all of his bastards by noble women.
