Cariaga Sin was a Jedi of the Human species (a female), existing during the eras of both the Mandalorian Wars and the Jedi Civil War.
Around 3963 BBY, Cariaga attended a meeting convened by Malak, at approximately the same time that Revan made the determination to involve the Jedi Order in the Mandalorian Wars. Others present at this gathering included Meetra Surik, Bastila Shan, and fellow Jedi such as Talvon Esan, Nisotsa, and Xaset Terep. Ultimately, Cariaga chose to disobey the directives of the Jedi High Council, and instead joined Malak and Revan in their conflict against the Mandalorian Neo-Crusaders.
Within the Exile's vision, she was seen utilizing a blue-bladed lightsaber.
