Cariaga was present during a gathering called by Malak, around the time Revan decided to involve the Order in the Mandalorian Wars (circa 3963 BBY), along with Meetra Surik and Bastila Shan, and fellow Jedi Talvon Esan, Nisotsa, and Xaset Terep. Cariaga herself ultimately elected to defy the Jedi High Council, and to go to war with Malak and Revan against the Mandalorian Neo-Crusaders.
In the Exile's vision, she wielded a blue lightsaber.
Cariaga Sin's face is one of the available female faces for the Jedi Exile, to be chosen by the player at the start of the game. If the player, as a female, chooses her face, then Sin's face would be replaced with another.
