A slaver gang known as the Bloodreavers are terrorizing the countryside from their base deep in the labyrinth under Thunderspire Mountain. But these slavers are only the symptom of a larger threat in the bowels of Thunderspire.
In ages past, the wizard Karavakos made a deal with devils, which resulted in him being trapped in an extradimensional pyramid, unable to escape. His only hope for escape is to lure adventurers into the Pyramid, in hopes that they will destroy his splinters and return his power to him. But his wife Vyrellis, whom he slew in a rage when the Pyramid formed, still lingers in spirit and wants nothing more than to see him laid low... Although set to allow PCs to just fight through each encounter, tips are included for PCs negotiating with the factions trapped in the pyramid.
Darkness looms near Winterhaven! Kobold brigands have grown ever bolder in their attacks, marauding the once peaceful town, and a known explorer has been missing ever since their departure to the excavation site of a dragon burial site. When the party investigates, they will discover that the kobold's leader, Irontooth, bears a tattoo of a ram-headed demon. This is a troubling portent, for the townsfolk will report that this can only mean the dread god Orcus, master of death, has an active cult in that ruined keep! It is up to the party to enter the Keep on the Shadowfell and put a stop to the cult's fell machinations before it threatens all the realm. There they will fight the evil priest Kalarel, Scion of Orcus and seal off the vile portal to the dark realms he is master of. Should the heroes seize victory, glory and treasure are sure to be theirs. But first they must endure the challenges of that dreaded KEEP ON THE SHADOWFELL!
