In case you’re wondering, I’m referring to her alternate portrait in Mercenaries — the one that you can get via the achievement by summoning the Golden Monkey in the fighting pit.
So, the question is: what is she and why does she seem to have red eyes? Is she a Venthyr there (doesn’t look very much like one, but I’m no expert here), and, if so, how exactly did she end up becoming one? Or is it coloured contact lenses (she’s famous for her glasses, but why stop there? 
), meaning that she’s cosplaying, probably at some kind of masquerade ball (in Castle Nathria, for example)? Or something in that goblet, perhaps?
