Crimsonwood 2

Well see, that's kinda what I was getting at: If it were just the thief guy, no surprise, but all of them are obscured in some way. The Stormbreaker captain, if you ask me, looks like he has a fake jaw (a la the Baron)

I suppose the light thing makes sense, but it's not exactly bright around Crimsonwood (then again, bright's a relative term.)

Define "obscured in some way" for each of the Grandmasters; I don't see what you're talking about. A fake jaw isn't obscurity. It's a replacement. Or in the case of your Baron, a replacement coupled as an augmentation.

Also, the light sensitivity thing is pretty dubious. Looking at Elpam Gorlab, or even better, O-pongo (December Event 2007) didn't really seem to mind the light. And I believe O-pongo operates most often during literal daylight hours in the Versal, where everyone else (Versalian residents) would be celebrating their sun. The Nightshadow Grand Master's outfit can be explained as playing the part, and I believe Mr. Broadrim is a techie.
