He is one of the founding members of Raya Lucaria and wears dark ragged robes and cloak with deep blue glintstone growing from the shoulder and neck. His head has a large glintstone eye growing on top of it, partially wrapped in bandages, as his brain is turning into glintstone. The large eye resembles the eye embedded within the skulls of Astel Naturalborn of the Void and Fallingstar Beast.
Lusat is part of Sorceress Sellen's questline where she asks the Tarnished to locate his body. Upon finding him, he will give the Tarnished his signarture spell - Stars of Ruin.
