The chapel, once populated by the priests and priestesses of Eldath has now been desecrated by cult of necromancers who sought its secrets to prolonged life. They soon discovered the bodies of the chapel’s clerics they slew, and those interred in the catacombs below, were unnaturally strengthened and preserved by the chapel’s white waters. Their bodies were soon used to create powerful undead. Seeing this desecration of her followers, Eldath stemmed the flow of her life-giving waters. The cultists remain in her chapel, seeking to corrupt the well and harness its powers for their vile plans.
Madness in Freeport, the final part of the Freeport Trilogy, details the final confrontation between the PCs, the Brotherhood of the Yellow Sign, and Sea Lord Milton Drac. In Part One, the Drac invites the PCs to the Grand Lighthouse Ball. Careful investigation can reveal the secret purpose of the lighthouse. In Parts Two and Three, the PCs must recover a powerful artifact to thwart the Brotherhood's plans. They must pass through an infamous pirate's hidden caves, then search a sunken temple of the serpent god Yig. In Part Four, the heroes must enter the Grand Lighthouse, AKA Milton's Folly, in a race against time to stop the Brotherhood's world-shaking master plan from coming to fruition. (Bibliographic note: This adventure was originally written for v.3.0, and later updated to the v.3.5 rules. The revised versions of Death, Terror, and Madness in Freeport were reprinted in an omnibus edition, along with two shorter filler adventures, as The Freeport Edition: Five Year Anniversary Edition.)
"Temple of the Deep Ones" is the lair of a group of deep ones and their god, suitable for four or five 7th-level characters. This adventure can be finished in one session. Ship captains report that a mysterious island has surfaced in the middle of a heavily trafficked trade route. Worse, ships that venture too close to the island are assaulted by a terrible creature and its servants. The island is disrupting trade throughout this part of the world, and several ships have already been lost. Unbeknownst to those that know of the place, the island rises at the will of Shar-Ngolyeth, a long-lost deity also known as That Which Lurks Beneath the Waves. The island is populated by a cult of deep ones and the beasts they have subjugated in the name of their dark god. The creature responsible for sinking ships is an aspect of Shar-Ngolyeth, a kraken. It is not meant for combat encounters; it's largely a plot device in this encounter.
