Sin-Eaters, also known as the 'Bound', are mortals who have died, but made deals with strange, alien spirits called 'Geists' to return to life. This does not come without a price; they must share their body, mind, and desires with the geist, and often spend as much time confronting the death around them as well as appeasing their new "friend" as they try to continue their own life.
Chandler Ombre served in the military with Léon Barnes who he calls a friend. He is about twenty-five years of age and like many of the people of Vindex, has considerable military type training.
He came to Lutetia with Barnes and has been worked for Vindex for two years. During his military service he had a near death experience. During this experience he made a pact with a geist to survive. Being one of the bound allows Chandler to see spirits of the recently deceased and spirits who have choose to not move on for one reason or another. Their appearance sometimes assists him in solving crimes in and around Lutetia.
Chandler's geist is one of the torn because of the way he died. The torn are called the 'Bleeding Ones', and the victims of malice, and they are those who die from violence. Their patron is the Red Horseman, and they are those who are killed by murder or other violent means, such as stabbing, shooting, or particularly traumatic and damaging deaths. Chandler's geist takes the manifested form of a bride wearing her white wedding dress. The dress is stained down the front and her throat is torn open. The geist often torments him when she is displeased with him.
