Why would it be Anna Valmont?
...
I figured, "artistic license".

(If
they can draw anything these days and call it artistic license, why can't I do the same with interpretation?)
The sword is probably The Sword (one of).
Murphy has been known to use a Sword, can't think of any other female Sword-bearers...
Valmont is not someone I picture holding a sword affiliated with the White God. She pillages churches for a living, doesn't she?
