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

Chapter 1 - When a relative of someone close to the characters goes missing from a nearby village, the players are asked to investigate. The party has to recover stolen goods from a thief before setting out from the City of Ravens Bluff. They travel through the wilds of Vesperin in search of the missing person, finding trouble and helping locals along the way. Chapter 2 - As the journey continues, the party arrives in a small hamlet suffering from a strange blight. The players will need to investigate the situation and choose sides in a longstanding feud between the mayor and a local magic user. Chapter 3 - After clearing a tribe of violent orcs from a nearby mountain pass to protect the residents of a town, the party will have to enter the lair of a long-dead dragon to rescue their quarry from a band of goblinoid slavers, where they discover an entrance into a dwarven city, lost and forgotten centuries ago. Chapter 4 - The party will have to traverse the ruins of the dwarven city, avoiding hazards and battling the horrors that lurk there, to uncover the identity of the slaver's leader. A discovery that will lead them through a treacherous forest to the city of Tsurlagol in search of a pirate ship called the Star Carver, and its drow captain, The Viper's Kiss. Along the way, they meet an unlikely ally. Chapter 5 - Once they arrive in Tsurlagol, the players will have to choose between gaining the assistance of the city council to fight the pirates head on, or making a deal with the Viper's Kiss, herself. The path they choose will either lead to an epic battle on the Sea of Fallen Stars, or into the deadly sewers and tunnels beneath the city to face an enclave of wererats, undead, and a tribe of mad, kraken-worshipping kuo-toa, in search of a fabled relic.

An omnious encounter with a fortuneteller sends a party of adventurers on a 200-mile journey across the Lands of Intrigue. While traveling throught the towns and terrain (detailed here for the first time) that lie in their path, they hear rumors and obtain clues about their mission. Their ultimate destination is Castle Spulzeer, a once proud stronghold that has become a den of terror. When the heroes enter the haunted keep, they meet a terrifying trio of residents: a madman armed with stolen magical power, a liche whose secret laboratory houses untold horrors and treasure, and a furious ghost bent on revenge. These three ensnare the party in their fight over an ancient weapon. Each will stop at nothing to keep it from the other two. The heroes must choose with whom they will ally - and the wrong choice could lead to their doom. Castle Spulzeer is an adventure complete in itself. However, as a crossover story, it offers every Dungeon Master a choice between two endings. The first leaves the party in the Realms. The second transports the characters to the Demiplane of Dread, where the plot continues in the Ravenloft adventure The Forgotten Terror. For 4 to 6 Characters of Levels 8-12 This conversion guide allows DMs to run the original module with 5th Edition rules. To use this conversion guide you will need a copy of Castle Spulzeer, originally available in hard-copy and now for sale in digital format on the DMs Guild. Visit Classicmodulestoday.com for instructions on creating your own classic module conversions and selling them on the DMs Guild. Castle Spulzeer was originally scheduled for publication by TSR in June 1997. Then, near-bankruptcy caused a total failure of TSR's schedule, resulting in no books being published from February through the very end of July. Some books would be delayed for over a year, and others would disappear altogether, but Castle Spulzeer was relatively lucky: it was just delayed four months, until October 1997. The reason may well have been its theming, and its crossover with the Ravenloft line, which made Castle Spulzeer a great Halloween release. Castle Spulzeer has an even more far-reaching connection: its ending can lead players to the demiplane of Ravenloft and The Forgotten Terror adventure. This was probably intended as a bit of advertising for Domains of Dread (1997), the third edition of Ravenloft which was released in August 1997. In other words: in their last days, TSR was working very hard to cross-market their products, but they didn't live long enough to see the success of the Spulzeer-Intrigue-Dread connection.

Gray Mountain lies deep in the lush elven forest. The temple there was a haven of meditation and learning - until taken over by an evil cleric known as the Rahib. Far under the mountain, he paces before the temple's great altar. A brown-robed servant rushes in and falls to his knees, trembling at the sight of the Rahib's black panther. "Rahib, adventurers came to the village as the sun rose - the strangers now protect Rahasia." A scowl crosses the Rahib's face. "I must have Rahasia! Attack again tonight." As the servant scurries away, a deep growl rises from the giant cat. Gripping the panther's leash, the Rahib paces again, speaking out loud. "We must dispose of these strangers quickly; the secret beneath the temple will not wait much longer." Note: the setting is unspecified, but certain tie-ins, like the wines, prefigure Ravenloft.
