I'd heard rumors of the Many-Arrows leader Vasni Bloodscar, having somehow gotten a spellscar. But why would some of her warriors have them as well? How could so many of them have gotten them without leaving the district? I don't know what's happening, but I don't like it.
Head along the road eastward to the guard post and speak to Captain Janros about this. maybe he can make some sense of it. And even if not, he should be warned.
