Mimic Madness is a psudeo-adventure with four interesting mimic encounters. These four encounters are structured in a way that they can be used together as one adventure, or each individually dropped into any adventure from EL4 to 7. The encounters vary the mimic's tactics significantly, such as by having them we a weapon rack that wields the weapon it holds, pretending to be animated furniture using its ability to speak, and pretending to be a floor covering a pit; none of them rely on the typical chest or door mimics.

The End of the World Is at Hand! A hideous death cult has seized control of an ancient artifact-monument known as Tovag Baragu. The power behind the cult is the Old One himself, Iuz the Evil, demonic master of an empire. He's on an all-or-nothing quest for supremacy over the world—and the heavens beyond. To stop him, heroes must face horrors never dreamed of, journeying to a shadowed city where Death rules and the living cower. Here, Iuz will achieve his mad dream by destroying the imprisoned master of that alien citadel: Vecna, the mightiest lich, an immortal demigod. Two items exist with the power to stop Iuz—the Eye and the Hand of Vecna—but using them carries fantastic risks. Not even the gods know what will be unleashed when these items are fully activated. Die Vecna Die! takes the heroes from the Greyhawk campaign to the demiplane of Ravenloft and then to the Planescape city of Sigil. However, none of the material from those settings is required for play. TSR 11662

For the past several days, dozens of strong earthquakes have rocked the coastal area surrounding the underground Temple of Poseidon. Since the first quake, there have been a growing number of reports of strange events and macabre occurrences throughout the area. Several families near the temple have abandoned their farms and refused to return. They claim to have been terrorized by inhuman specters who prowled about their farms late at night. One of the farmers says he found a farm animal crucified and eviscerated in a ritualistic fashion on his front porch. Following the first tremors, all communications with the Temple of Poseidon, seemingly the center of the troubled area, were cut off. Messengers dispatched to the temple to request guidance from the Holy Oracle located there have not returned. Now the darkness has spread to this town. Unnatural births have occurred. Strange cries can be heard in the night, and there is a cowl around the moon. Magical divining has proven useless in naming the dark forces that invade. Many of the townspeople have already abandoned their homes and those who remain have but one recourse left: They have sent out a cry for hardened adventurers, experienced in dispatching evil. They must travel to the temple to discover the fate of the men there, and, if possible, elicit their help in destroying the growing heinous power. Pgs. 31-46
