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 (道德經). He states to the player that Midea reads the quotes to him from a book, though he never names it.
"I'm not cheery, really. I've just accepted my role here. I found a book once. Midea read part of it to me. It said: "The Master doesn't try to be powerful; he is powerful. An ordinary man keeps reaching for power and thus never has enough.""
"I'd like to be free, but I'm not. And the harder I cling to that idea, the more miserable I'll be that I'm stuck here. And this work is hard enough without extra misery. Speaking of which, I should get back to it."
