Explore an abandoned wizard’s tower in this short mini dungeon! This adventure is a Micro Dungeon. Preface Long ago a wise wizard named Adubeus lived deep within the forest. As he lived, he would pass out nuggets of wisdom to those in need, and aid the local townsfolk in times most dire. Long past are these happy days, however, and the kindly old wizard has not been seen in many decades. Some say he found a calling elsewhere in the world, while others whisper of his demise at the hands of a secret experiment gone awry. One thing is certain, however. His tower, long forgotten, still stands out there in the forest. Occasionally, some hapless person wanders upon it much to their personal peril. The specific details of Adubeus are left vague on purpose. This small adventure is intended to be played as part of a larger campaign, and the location can be modified to fit your setting. The reasons for your adventuring party to be heading towards the tower are entirely up to you, however, below are some good sample adventure hooks.

Eons-old secrets slumber beneath the forbidden Ghost Ice.

Strange machines and wonderful horrors stir beneath the ice… Frozen in Time is a level 1 adventure for any DCC RPG campaign.

This adventure takes place in the Moonsea of Faerûn. The players have been brought to Melvaunt to search for the missing scions of the city's great families. To the north, in Thar the orc tribes converge on the ruined fortress of Xul-Jarak, flocking to the banner of a charismatic warlord. There, he intends to sacrifice the scions of the great families of Melvaunt in a bloodritual to Gruumsh. The players will escape Melvaunt, search along the wilderness of Thar for the Fortress of Xul-Jarak, and then explore the dungeons of the ruined fortress and hopefully rescue the scions before they are sacrificed. There also is a Web Enhancement by Eric Cagle on the archives of wizards of the coast's website designed to scale the adventure to level 8. For example, it replaces the Owlbear with a Tyrannosaurus. This is an easy to scale adventure with much of the player's difficulty coming from intelligently avoiding problems, choosing how to approach each floor in the most tactical way, and quickly adjusting when something goes wrong. The adventure has sidebars including common orc battle cries (In Orc!), ready to use orc names, weather and random encounter table in Thar, a description of what happens if the party fails or partially succeeds, and suggested minis for each of the encounters. There is even an extended description of the bloodspear ritual, an event the party is not meant to encounter in a normal run. The appendix is detailed for all the humanoid characters including the scions and their equipment, the named villains, and variety of unnamed orcs the party will encounter. The fortress also offers an opportunity to introduce the players to the Underdark and the Zhentil Keep. There is a passage to the Underdark the players can accidentally explore, and return to later. Emissaries from Zhentil Keep have come to watch the ritual and have their own motivations. These npcs provide an opportunity for exposition and role playing at a point which otherwise might be combat heavy, acting as a valve for the first floor - helping or hurting the party with subtle magic should the difficulty be off.

Dungeon Masters Kit - Number 1 Palace of the Vampire Queen For three centuries the peasants of the Dwarvish island of Baylor have feared the raids of the Vampire Queen and her minions. Sweeping down at night from the palace in the shrowded peaks of the island, they range even further in their search for blood. And not only blood - the children of dwarf peasants often disappear if they are so unfortunate as to be out at night. Even the cities are no longer safe. The most recent victim was the Princess of Baylor, daughter of King Arman, who was taken in a midnight raid on the capitol city of At Toe within past weeks. King Arman has offered fabulous riches and land holdings with titles to the person or persons who can brave the stronghold of the Vampire Queen and return his daughter to him alive and well. But, in truth, he holds little hope. For even King Arman, Ruler of Baylor, Defeater of the Ten Orc Tribes, is afraid in his heart to face the Vampire Queen.

From The Magazine: "Every summer, Duke Hightower holds a competition quite different from the traditional jousting and archery tournaments held by similar lords of his station. The rules of his tournament change from year to year, and, to oversee the games, the duke has appointed two wizard brothers who help choose the setting and create the rules and challenges of the competition. This year the competition is called the “Owlbear Run,” an overland race that requires each participating team to escort a live owlbear from the town of Telvorn to the town of Milvorn. The teams will face a variety of challenges; some are devised by the wizards, others by the competing teams or their sponsors, and some occur entirely at random. All of these tests are in addition to the challenges inherent in motivating a temperamental owlbear. Fortune and fame await the first team to cross the finish line, and the local lords sponsoring the race are eager to enlist skilled champions for their causes." Pgs. 2-27
