Hey gang. My players have blown off a module (DCC #23, Sunken Ziggurat) 3 times, and now I need to figure out a plausible result.
As you know, the module says that there are "Spirits of Uru-Nuk" being created by a defiled altar, deep in the ziggurat. These are created 1 per round
(the encounter area near the top of the ziggurat explains that they come this quickly and it will be hopeless to stand and try to take them all on). If I follow that text, approximately 864,000 spirits have flown out into the world during the 2 months the PCs have ignored this module.
I'm using the revised spirits from the Dungeon Denizens PDF. The Spirit of Madness is a CR 4, casting hypnotic patterns, confusion spells, and its touch can reduce wisdom to 0 (catatonic, nightmares). The Plague Spirit is a CR 5 and casts contagion. The Storm Spirit is CR 6, hurls 1 lightning bolt per day, and slams for shock damage. They all have DR 5/magic, and elemental traits.
What is the logical conclusion of ignoring the ziggurat's rise? Do I really keep this thing creating 1 spirit per round? Would someone intervene before the numbers got huge? Are towns & villages destroyed? On what scale? How bad do you imagine this could get?
One last twist. In my campaign, I have Tiamat as very much alive. The module portrays Tiamat as dead and the ziggurat may feature in Tiamat's rebirth. Since in my game Tiamat never died, I've toyed with putting Zargon in there instead. There is a 3.5 edition conversion of Zargon
(he's more than halfway down the page, with the description of room #100), if that helps you to get a feel for him. It's a possibility, if you find that to be an interesting path to consider.
I'd love to hear your thoughts. Thanks.
