The GM:
HAVING SAID THAT, I was thinking of maybe having the elven banshee be sort of the immediate neighbor of Winter the Death Knight? How does that grab you, Winter...?
I have just been informed that Trina is not of elven heritage, and that was, instead, just an idea I got in my own head at some point, that banshees would be much more likely to be elven.
So, never mind. You won't be "neighbors."
Gryux/Bill plan is still on, though.
