Brink of Madness
From our recent Dungeon Magazine article:
The world is imperiled. An insane wizard works to rip open a hole in reality to unleash the Far Realm's abominations and plunge the world into madness and despair. If he succeeds, chaotic energy washes across the world, altering all it touches. There isn't time to raise armies, not a moment to call forth the gods' servants, so close the wizard is to achieving his goal. It falls to a band of courageous adventurers to stand once more against the horrors of what lies beyond.
