War torn, the plane sees a lot of corpses pile up and the ground is pretty hard to dig into. One of the ways the plane disposes of this once-sentient trash is by the beaks of the Birds of Thorn. Despite the pompous name, derived from the addled wizards that created them to watch over his tower, but then suddenly died of heart attack, these birds have no thorns whatsoever adorning them, as do so many lower planar creatures. They compromise ravens, vultures, sparrows, ducks, and whatever other kind of animals known in the Prime. These creatures now possess a slight modification to their diet and physiology; they became carnivores and their beaks are entirely made of sharp, light steel to crush through the armor of fallen warriors.
Wichmann? He's an odd one. No matter the stories, the metaphors, or simply telling him what I know, he just won't learn. It's like he starts the day with a drink of Stygian *tea*.
