This is Livia from Hell's Rebel's campaign. This is the only time in a full campaign she wore a dress, not a sword
It's at the point where the team visits Vyre and is trying to politic their way into getting the governors to support Kintargo's bid for independence.
I started this last year... yeah... so... cleaning up my files and... OOOOH!
And... Ive lost the ref to her dress. If someone points me to the right direction Ill gladly link.
