Overview
Damian is a member of the Brighthaven Triarch during Vianna's youth. He, Olivia, and Isaac assign Isaac as Vianna's protector after her power becomes public and try to keep Alistair from using the belief that Vianna is Pyrathalor's reincarnation to push Brighthaven into the Brighthaven Civil War.
Vianna's Rise
Damian has prior contact with Marcus before Vianna enters Radiance Prime Magic School, and Marcus knows Isaac through him. Brighthaven already has public talk about Isaac joining the triarch after Damian.
As Vianna's power becomes public, Damian and Olivia attend her training and tournament. After Vianna wins as a level five fire and ice mage, Damian, Olivia, and Isaac discuss the danger around her in private. Damian gives Marcus only Isaac's protector assignment, keeping the full concern from him, and warns that Brighthaven cannot afford the Brighthaven Civil War.
Civil War and Death
Damian and Olivia decide to speak with Alistair to prevent the Brighthaven Civil War from starting. The attempt fails. Damian tries to hold Alistair back and dies during the opening violence of the Brighthaven Civil War. Olivia also dies in the Brighthaven Civil War.
Years later, Julian uses Damian's name while luring Vianna onto a Brighthaven construct boat. Julian's lie that Damian is eager to see her exposes the trap because Damian has been dead since the escape from Brighthaven.
