Orpheus does not talk much about his past, prefers to keep his mind on the present and future. Has worked for years as an assassin and manipulator of sorts. Got the nickname the Sun Killer due to the way he took out the Sun Kings, a crew of thugs who worked for The Respect in the city state of Vice. The group did not leave the hideout they occupied, so they used artificial magical sunlight. This was a very well known fact and made taking them out very difficult.

Orpheus was hired to assassinate the Sun Kings' leaders. He snuck into the citadel and was able to dispel the magical sunlight, and from there took out every member of the group. After these events, the public did not know that Orpheus was the one who did it, so they came up with the name “The Sun Killer” to refer to the assassin. Orpheus has since taken a liking to the name, so has kept it as a moniker. It also serves as a way to demonstrate his skill and reputation.

Has believed and followed the Raven Queen since he was young, and his faith has grown significantly over the years.
