It's no secret that demons are pretty much my favorite monsters in the game. When we were brainstorming ideas for regions to include in Golarion, the concept of a realm where the demons had invaded and now ruled was near the top of the list. In fact, we ended up with two regions where the demons are in charge—the smaller of the two being Tanglebriar in southern Kyonin (a region more or less transplanted directly from my homebrew world), and the much larger Worldwound itself. Whereas Tanglebriar was basically the work of one nascent demon lord, and as such was relatively limited in the scope of its area, the Worldwound was the work of a full-on demon lord, Deskari, and the resulting demon blight is correspondingly much more massive.
We've tinkered here and there with the Worldwound over the past few years, but with the Wrath of the Righteous Adventure Path, we're finally diving into the deep end of the demon-haunted pool. Which means the time is finally write to head on into old Sarkoris and explore it. Aptly titled The Worldwound, this 64 page Campaign Setting book aims to do exactly that. Of course, it covers the entire demonblighted region—even though Wrath of the Righteous remains pretty tightly focused along the northeastern border, The Worldwound has a lot more secrets to reveal.
There's plenty of new demons and monsters lurking in the Worldwound, as well as in the pages of this book, as evidenced by the creepy monster pictures that grace this post, but even the plants in this realm want to kill you. Take, for example, the following excerpt from the book's chapter about Adventures in the Worldwound:
Leechweed (CR 3 hazard): These plants cluster thickly in the muddy marshes of the western Worldwound, typically growing in a 5-foot-square patch. A single plant is slightly smaller than a human hand, and consists of a mass of dark green leaves from which a single feeding stalk extends. The tip of this stalk contains a small, lancet-like protrusion that can pierce flesh with ease. Spotting a patch of leechweed before blundering into it requires a DC 17 Knowledge (nature) or DC 22 Perception check. A living creature that comes into contact with a patch of leechweed swiftly learns the source of the plant's name, as dozens of feeding stalks suddenly stab and slash at any bits of exposed flesh. As soon as a creature is in contact with leechweed, the plant attempts an attack against it with a +9 bonus. The attacks continue at the end of each of the creature's turns if it doesn't move away from the plant. On a hit, the plant deals 1d4 points of damage and 1d6 points of bleed damage. Fire kills leechweed, as does holy damage or any magical effect that specifically harms plants (such as blight).
That, in a nutshell, is the Worldwound for you—a place where even the grass wants to kill you.
