Die, Vecna, Die!

Die, Vecna, Die! is a second-edition Dungeons & Dragons adventure, year 2000, by peak Bruce R. Cordell and Steve Miller. This is what propelled archlich Vecna, already awesome, to the Greyhawk pantheon. Unlike some modules in recent memory, these two authors kept the PCs at the forefront.

The party starts at Tovag Buragu across the Hellfurnaces, one of the old-school Greyhawk mysterious settings, which hosts rifts through time and space. These lead to a network of planes including an easter-egg shared with Queen of the Demonweb Pits: the Pink Ocean. Also: true ghouls from Wolfgang Baur's classic "White Kingdom", Dungeon #70. Ultimately, the PCs need Vecna's home demiplane Cavitius. That's through Cirithburg, and its Adytum.

Cavitius is an agreeably horrid part of the Dread. The highpoints in Vecna's palace are, of course, his sundry mummified extremities which the party members can try on, including the Head.

Lastly, Sigil for the showdown.
