Classic Dungeon Trivia 4

I'd like to thank Christopher B for waiting nearly 2 1/2 hours before answering last weeks Classic Dungeon Trivia. I swear I'm trying to make these somewhat challenging, but it's just not turning out that way. Lets try another before I get really serious with you guys.

STEPS OF THE ZIGGURAT If the group reaches this point they will be able to see low altar stones with shells upon them. There are 2 such containers on the first tier of the ziggurat, and other pairs on each successively higher altar. Each tier of the pyramid is 12' high, and the steps are steep. These steps must be ascended by all creatures passing through, so that homage can be paid to the goddess, an offering paid, and passage continued elsewhere. Groups coming in from other tunnels are held in waiting areas while appointed representatives perform the necessary obeisance.
