As we approached the burning village...
No, I don't know how. I'd imagine one of them cast Ignite, or that they struck flint against steel the way most people do. But whatever the barriers were to lighting the village on fire, those arachnids were determined enough to overcome them.
Anyway, as Samiel (my spider, if you recall) and I approached the burning village, we were just in time to see a pyre being built around a half-paralyzed woman.
<She is begging for her life.> I sent.
<I don't care what they beg for, unless it's to be put the flame.> replied a spider decorated in black and white bands.
<She's got a decent drive for vengeance, as well.> I told Samiel.
<Unlike me, she won't listen while...>
A brown and red spider turned enough to latch a thread of web to my arm. When she pulled, so did I. It should have yanked her right to me, rather than tearing the skin off that entire section.
