No-one knows why, but many of the villagers of Greenmist have been going insane. Not only that, but something has caused the surrounding environment to transform into fetid swamps. Heroes from far and wide have gone into the swamps to destroy the source of the madness, but none have returned. The truth is that the psychic whispers of an aboleth have invaded the minds of Greenmist's people. The creature called Seedooloo has been using forbidden magic, mad science, and the strange ability of his kuo-toan worshipers to grant himself the power to drive the surface world to insanity. The Call of Seedooloo includes monsters found in Mordenkainen's Tome of Foes.

Those friendly dwarves were the first to go, the poor things. And now the beast has been killing and eating the people of Brandonsford. No-one wants to leave the town's walls. With the humans out of the forest, fairies have taken over, and now the goblin king Hogboon seeks to claim the entire forest as his new kingdom.

For centuries, the volcano now called Mount Zulgar was the battlefield of a conflict between red dragons and frost giants. The final battle saw the extinction of the dragons and only a handful of living giants. The dwarves of the Frostblood clan used this opportunity to drive out the giants and take the mountain as their own for its rich deposits of gold. 100 have passed, and now the volcano bubbles to life once more, bringing with it all manner of fiery creatures. Miners have been killed, and implike monsters assault the citizens of the mountain. The master of the goldsmith's guild has called upon your party to snuff out the Fire in the Frostblood Mine. Fire in the Frostblood Mine is a 4-5 hour adventure for 4 3rd-level characters. It can be used as either a one-shot or as part of an ongoing campaign. This module includes a single-session adventure to introduce your players to the strange creatures of the inner planes, maps of the two levels of Frostblood Mine, and a unique sentient magic item.
