@Korin I'm not the GM or in any position of authority, but from what I've seen in the character sheets it seems like a wide variety of things are accepted. I would just try to write it out and give it a shot to see if the GMs agree with it. It doesn't seem like we have a character specifically like that, either.
Edit: about Ursula's ability to notice Damien's spirit companions, I worked with
@GingerBoi123 in PMs to decide if Ursula could see them or not. We came up with the conclusion that she could see them faintly, and he was alright with my description of what Ursula herself could see. This doesn't mean everyone can see them, or even that they see them in the same way that Ursula does. I would talk to
@GingerBoi123 himself if you ever decide to interact with Damien.
Re-edit: In my posts I often refer to any meta/supernatural/etc. characters or npcs as "Inhumans". That's how Ursula sees and refers to them, and herself, as. They might be called something differently by other people. I also refer to normal humans as "Regulars".
I also came up with the level of technology we could possibly have as: high-tech phones and holo-papers (meaning, holographic, self-updating newspapers that only broadcast the most up-to-date news). Maybe only a small amount of places have these, or maybe everyone does, that would be up to the GM/Co-GM to decide.
