GURPS: Red Sky
A new priest at St. Joseph Old Cathedral, Cristián Arreaza is very clearly aware of the more supernatural elements of the world. On 5/5/2014, he enlisted the aid of Wizard Solomon and Sofía Torres to aid in an exorcism, revealing after the fact that this is the fifth or sixth such occurrence in the last three weeks.
As of Chapter 5 of “Clean Slate” (10/30/2016), Sofía is aware that he has some sort of connection to an entity known as Anael. She does not know the specifics.
