Scarred Lands

A grimbright Dungeons & Dragons setting released by White Wolf under their OGL license subsidary/front "Swords & Sorcery". Involves a world devastated by the war between the Primordials (immensely powerful "Elder Gods") and the Gods (younger, weaker but more mortal-friendly deities), with the various mortal races having to live in it. Features one of the coolest twists on dying elves ever (they're dying because they took down a Primordial, something that mortal races should fucking not be able to do, and it cursed them all in its death throes), a sea polluted with blood because a Primordial's still-living sundered halves are buried in it, a swamp region filled with utterly psycho faerie-creatures & mutants, and is generally a "the world has gone to shit, but it can get better and it is getting better" kind of place.
