Hopefully this is in still under the wire. If it helps I'm on Pacific time and forgot about the zone difference.
I'm still working on some details but Miren is an elven arcanist, Void school savant.
This is a second application and pairs with Sigrun. Having gotten in to creating Miren though, I think she might be my slight preference of the two.
Yeah, both my applications have fairly detailed backgrounds but they stop some undefined time before the beginning of the adventure so no reasons are given for being in the asylum. I also expect that much to nothing of the backgrounds would be known to the characters at the start.
