The door to the Abyss can be opened with good intentions. An act of mercy released a creature of unspeakable evil. Now, only you have a chance to stop it. A vrock has been trapped inside a stone circle outside the village of Sundown. This stone circle remained untouched for thousands of years, until an unwitting mage decided to depetrify one of the standing stones that he mistakenly thought was a helpless farmer.

This module primarily is based on investigation and problem solving, with a final fight with the vrock at the end. Roleplaying should be emphasized.

Snakes fly, stones walk, and colossal monsters burrow in the world's crust - do these omens fore-tell catastrophe? Perhaps so, for now the dark elves walk in the sunlight, wearing armor that turns the shcaprest blades and strongest spells. They are poised to conquer the fabulous Hollow World. But what is this armor? How does its creation involve the ancient, mile-long Great Annelids, as well as those wondrous creatures, the feathered serpents? The mystery's solution draws your heroes across three thousand miles, from ruins to seaports, through the trackless caverns beneath the World's Spine, and finally to the eternal land of Nithia. There, your heroes discover the true meaning of... NIGHTRAGE! Nightrage is the second part of the far-ranging Blood Brethren Trilogy.

The dragonmen have taken Solace. Its beautiful tree houses lie black and battered amid the stumps of great vallenwood trees. Kapak Draconians, armed with poisoned weapons, enforce a brutal martial law on the survivors. And Solace is only one outpost: the dragon armies control the plains. Only the elven kingdom of Qualinesti stands unconquered. The rest of the plainsmen suffer the most: a long slave caravan hauls hundreds of them to the fortress prison of Pax Tharkas. "Dragons of Flame" is the second in TSR's series of Dragonlance adventures for use with the AD&D game system. Your players will adventure in the world of Krynn and visit strange places such as Qualinost or the Sla-Mori, encountering bizarre draconians and disgusting Aghar. They can play the modules as a set of separate adventures or as a great quest that spans the entire Dragonlance story. Art by Jeff Easley. TSR 9132

Introductory adventure for Dark Sun, included in the original box set. PCs start on a slave caravan but are freed when it is attacked. With limited equipment and water, they must cross the desert to an oasis then save a druid. As with many Dark Sun adventures, uses a flip book providing 24 maps and illustrations for players. Combines combat encounters with survival encounters, where the treasure may just be food or enough water for another day.

Enter the ancient and corrupt city of Tyr, whose tyrannical sorcerer king has ruled for a millennium. As you wander the city, from the wreck of the Elven warrens to the sanguine splendor of the arena, you realize that the citizens of Tyr thirst less for water than they do for freedom. Now, after a century of slave labor, sorcerer king Kalak's great ziggurat nears completion. He has promised the city a grand celebration when the monument is done, complete with the most brutal arena spectacle in Tyr's long history. Rumors abound as to the nature of the spectacle: some believe it will bring with it the longed for manumission of countless slaves: others fear the annihilation of Tyr and her people as a sacrifice to Kalak's hunger for power; and a secret few believe it will be a day of revolution - a day of freedom. The adventure that introduces the Dark Sun setting as well as part of its metaplot. The adventure starts with the PCs being enslaved and forced to work on Tyr's ziggurat, where they make various connections that can affect things both in this adventure and the next in the series (Road to Urik). The finale takes place simultaneously with the finale of the Verdant Passage novel, and has something of a disaster movie feel - major events are happening, and the PCs are trying to survive in their shadow and (hopefully) save some people as well. Like many other Dark Sun modules, this adventure comes with a flip-book full of handouts as well as a few pre-generated starting-level characters. TSR 2401
