Evelyn is a "companion of pleasure" at The Staff and Coin Brothel in central Mor'Koc. She was one of the closest friends of Bel Kuko during the events of A Short Month after she became a regular at the bar in the brothel (it being relatively close to her home and cheaper than The Green Elf) and was the first person to rally people to her cause when her being a Crusader of The Nameless One became public.
Following Bel's ascension to godhood, Evelyn joined her church but retained her job at the Staff and Coin and as of 3A 206 remains working there.
