Lord Bartimos was a member of Queen Rhaenyra Targaryen's black council during the Dance of the Dragons. He urged the queen to use her numerical advantage in dragons to take King's Landing from King Aegon II Targaryen, but Rhaenyra agreed with the cautious Prince Daemon Targaryen. After the Treasons of Tumbleton by the Two Betrayers, Bartimos urged Rhaenyra to arrest the other two baseborn dragonriders, Ser Addam Velaryon and Nettles.
