Quentin Coldwater provides one of the most honest perspectives on what it is like to have depression. For him, it goes beyond sadness. It is a sense of nothingness, emptiness, a disconnection from one’s inner being. His battle is twice as difficult than that of usual fantasy protagonists, who are naturally self assured, brave and optimistic . Instead we have insecure, melancholy Quentin. A soon as he is done battling beasts on the outside, he must go on to fight those residing inside his mind.
