So basically a Fetch with a Demesne?
As it happens, the Ancient Sidhe Trickster from that alphabetical stunt list might be close. Tack on Demesne and there you go. Some of his stunts are overpowered, but not enough to cause trouble on an NPC.
If that doesn't work, let me know and I'll make something new. I've been meaning to get back to making characters anyway.
Is there anything unique that you have in mind for this faerie? Any unusual events or personality traits or abilities?
