A new, expanded, OSR-ised, prettified edition of Joseph R. Lewis’ Ragged Hollow Nightmare which was rated among The Best by Tenfootpole. Joseph Lewis hit a perfect balance between the classics of dungeonverse fantasy and the whimsy of the folk tales we love so much (as testified by our Folklore Bestiary. we released last year), adding a dash of dreamworld strangeness and a pinch of body horror to spice up his brew. We did our best to respect his recipe when adding our extra material (about 30 pages of it). We worked with Joe and Li-An (the perfect artist to give life to spooky Ragged Hollow and its strange surroundings) to make the best module we could: a solid introduction to old-school gaming for both players and gamemasters. And for the veterans among us, it also makes an excellent, full-fledged campaign starter. Nightmare over Ragged Hollow is a sandbox adventure centred around a quaint town at the edge of the kingdom. But however quiet life in Ragged Hollow is, the town lies between places where you shouldn’t be traveling alone. Places like Gloam Wood (“A witch or two lurk there!”), the Bleak Mountains (“I’m told there are bugbears…”) and their infamous Mount Mourn (“Home, they say, to cursed Dwarven ruins”), not to forget the Wailing Hills (“Bandits on every road!”). There’s even a haunted house by the river (“That mad inventor riddled it with traps!”). But only when an impenetrable dome of golden light materialises around the Temple of Halcyon (“Hey, my kids go to school there!”) do things really get out of hand. Some selfless heroes (or, failing that, a bunch of greedy ne’er-do-wells) should really get involved. One town with three adventure mini-sites Three small dungeons One 50-room dungeon Three hexes with 16 detailed locations Two groups of potential allies or rivals Sixteen pre-generated characters One deadly countdown! Written for the Old-School Essentials (OSE) rule system

"More than five hundred years ago, clans of dwarves and gnomes made an agreement known as the Phandelver’s Pact, by which they would share a rich mine in a wondrous cavern known as Wave Echo Cave. In addition to its mineral wealth, the mine contained great magical power. Human spellcasters allied themselves with the dwarves and gnomes to channel and bind that energy into a great forge (called the Forge of Spells), where magic items could be crafted. Times were good, and the nearby human town of Phandalin (pronounced fan-duh-lin) prospered as well. But then disaster struck when orcs swept through the North and laid waste to all in their path. A powerful force of orcs reinforced by evil mercenary wizards attacked wave echo cave to seize its riches and magic treasures. Human wizards fought alongside their dwarf and gnome allies to defend the Forge of Spells, and the ensuing spell battle destroyed much of the cavern. Few survived the cave-ins and tremors, and the location of Wave Echo Cave was lost. For centuries, rumours of buried riches have attracted treasure seekers and opportunists to the area around Phandalin, but no one has ever succeeded in locating the lost mine. In recent years, people have resettled the area. Phandalin is now a rough-and-tumble frontier town. More important, the Rockseeker brothers - a trio of dwarves - have discovered the entrance to Wave Echo Cave, and they intend to reopen the mines. Unfortunately for the Rockseekers, they are not the only ones interested in Wave Echo Cave. A mysterious villain known as the Black Spider controls a network of bandit gangs and goblin tribes in the area, and his agents have followed the Rockseekers to their prize. Now the Black Spider wants Wave Echo Cave for himself, and he is taking steps to make sure no one else knows where it is." Extra Info from AL.com users: by @marcellarius. "There are a variety of locations in this adventure: the town of Phandalin, a gang hideout, a ruined keep in the forest, a destroyed village, and Wave Echo Cave (a dungeon crawl). The adventure is written in a sandbox style and relies on the players to choose their path. Phandalin offers several side-quests which could serve as hooks for continuing adventures. The premade characters have ties in their backgrounds to NPCs and locations. If you're not using these you'll need to consider other ways to introduce key NPCs."

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
