In the city of Waterdeep rests a tavern called the Yawning Portal, named after the gaping pit in its common room. At the bottom of this crumbling shaft is a labyrinthine dungeon shunned by all but the most daring adventurers.

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

Synopsis: Chalk Hill is a lonely village on the edge of the Downs. Nearby barrows contain remains of long-dead kings. As is the local custom, a pair of young newlyweds went to the ancient standing stones for the druids to bless their union. They never came back. The heroes must find and return the couple, who have been taken into the grave of Eorl Wulfstan. The undead Eorl saw the new-wife in a dream, and she is the spit of his long-lost beloved, so he had his servants bring her to him. They slew the young man, who rose as undead under the Eorl’s control. Can the heroes find the survivor and put the dead back to rest? A 4 to 6 hour adventure for 4 to 6 Tier 1 characters—optimized for 5 characters of 3rd level. This adventure came about thanks to the generosity and encouragement of Dyson Logos, cartographer of Waterdeep: Dragon Heist. In it you'll find maps never before seen in a Guild adventure! "Chalk Hill" is an Old School "out and down" dungeon crawl, where brave adventurers venture into the wilderness and pit themselves against horrors which would set a-quiver the flesh of honest folk. It's proof you can have an OSR experience using the 5e rules!

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.

Listen up! You're in my dungeon now, Morty! On Earth C-141, I'm a LEGENDARY D&D adventure writer!
