Fire

Characters who came here from previous iterations of the game are aware of fire and how devastating it can be; more recently, the Donnelaith pack was destroyed because of a lightning strike and then a fire that swept through the Weald (which is also why the description of the Weald is different now); wolves cannot use fire / transport fire / start fires, but I'm sure there is a certain level of semi-realism that is appropriate. I believe at one point there was a cult-type pack that utilized fire? Or I could be thinking of another site, since the concept is quite common.

Hope that helps!
