Possibly the most esoteric Dresden Files costume to date: Warden Molly! An alternate-future version of her character based on a SINGLE LINE of text from "Proven Guilty":
"A third faced me in a grey Warden’s cloak, though a burn scar, almost a brand, marred the roundness of her left cheek."
I was so busy having a blast at MarsCon that I didn't notice I hadn't gotten many good shots of the costume, so I'll have to make a point of getting better shots if I reprise it.
Thanks to Blaze for the gorgeous cloak and Matt (the above Harry) for lessons in burn scar application.
