A Pitt slave for as long as he can remember, Adan is one of the few steel saw wielders content with his lot in life. This is partly due to the philosophical texts he reads when visiting Midea at her quarters. He feels that since fate has given him this life, he must make the best of it.
Adan spends his days in front of the entrance to the Mill, sawing away at a destroyed bus with his steel saw. This is all he does until the mission Free Labor, in which his body can be found in the same location, presumably killed during the chaos caused with the uprising.
His attitude is optimistic because he has accepted his role in The Pitt. The basis of his beliefs come from the ancient Chinese philosophy of Taoism, his quotes are based on their philosophical text called the Dao De Jing. He states to the player that Midea reads the quotes to him from a book, though he never names it.
