Sunken Ziggurat (Dungeon Crawl Classics 23)

The Sunken Ziggurat by Richard Pocklington, published by Goodman Games 2005 softcover. An adventure for character levels 5-7

A recent earthquake has exposed an ancient ziggurat long buried in the earth. When the heroes are called to investigate, they find more than just a buried structure. The dragon-queen Tiamat was slain on this site, and the ziggurat was built eons ago to seal her taint. Now that it has resurfaced, evil magics flow into the surrounding lands! The heroes must descend into this ancient edifice, defeat the monsters that dwell within its bowels, and replace that seal that prevents Tiamat's evil from leaking into the world!

Remember the good old days, when adventures were underground, NPCs were there to be killed, and the finale of every dungeon was the dragon on the 20th level? Those days are back. Dungeon Crawl Classics don't waste your time with long-winded speeches, weird campaign settings, or NPCs who aren't meant to be killed. Each adventure is 100% good, solid dungeon crawl, with the monsters you know, the traps you fear, and the secret doors you know are there somewhere.
