Acedia is a female character that appears to Havok in dreams. She is dressed in their rough battle coats, but is wearing it in a sexual manner of the front completely open and no clothes under. With long hair that obscures one of her eyes, she has a very down-trodden and slow appearance.
Despite what almost comes off as a lazy feel to her, her face and eye(s) shine with intelligence and questions Havok’s fatalistic view of events.
He describes her as incredibly beautiful, being both sexual as well as having a purity to her. This is an element he thinks is gone from the world.
Acedia is sometimes seen with a weapon, often a pistol, but never fires it.
