S.F. is Subtle, Heartless, Ruthless and Magnanimous. They’re a criminal mastermind. They’re a (literal) borderline-psychopath; they find it very difficult to feel any sympathy for anyone. They do occasionally feel some emotion, however, and that worries them–they try to take care of the people who evoke that sort of feeling in them, and to those people they often give random gifts, etc.
They’re obsessed with secrets; their ultimate goal is to step outside of time, in order to be able to see all truths and all fictions at once. They don’t know how to get there, yet, but they’re pretty sure it’ll require significant influence and finances to do so–hence their underworld empire.
