@Genkai I did some brain storming as to what I would put in a roleplay like this, and am more than willing to fill out a character sheet to go with it.
I was thinking a retired (or run away) assassin from a lord's or royal family's personal Arsenal. They'd be well versed in disguise, so the identity, alias, etc. They'd give to the rest of the party may not be true, and may be subject to change as they would be well versed in disguise.
As such, I'm super flexible with wherever this character would fall into place. I was thinking for the wind element. But I can fill whatever role is needed for the group :) No worries here.
