Vaas was born in 1984 on the Rook Islands and from a young age, he was a member of the native Rakyat. He was particularly close to his sister Citra and mentions that the first time he killed was for her. Since he was a child, Vaas was deeply infatuated with his sister to the point of obsession. He would commit violent acts against anyone who gained her affection, such as a man who he caught with Citra in bed. Vaas could never tell his sister how he felt which led to inner turmoil that led to his decline.
