There on is a member of the Seelie Court. He was encountered by Envoys of the Vatican City SAVE Office in 1936. He was found chained and tortured in the basement of an illegal gambling hall. There were signs that at least one member of the Unseelie Court had been present and may have been responsible for the condition in which Theron found himself.
The Envoys released him, but in return for a favor. With that agreement made, Theron is honor bound to provide a favor to each of Oliver Merbach, Lodewijk Van Beers and Tomas Gessner.
