Designed for DMs.
This puzzle was created to be used in an underwater location surrounded by a coral reef for a party of sixteenth level characters. The original location also happens to be the Southlands in the world of Greyhawk (the Flanaess) near the Isle of Dread. The deities and the deity’s name used in the puzzle are of the Olman pantheon. However, by making adjustments to the skill DCs, the locale, and the effects of the trap itself, the puzzle can be easily used in any locale for differing levels of PCs.
If you wish to use the Olman pantheon in this puzzle, you can find much more on the Olman deities in the articles “Aztec Mythos” in Dragon Magazine #352, #354, in Legends and Lore 2e, or at greyhawkonline.com.
