The Dread tunnels of Ruxbar were created by a cult of a lesser evil deity of the giant pantheon, known as Jargain to serve as a planar gate in hope of bringing chaos and destruction to the natural order of the world and power to the one who would control the gate. Ruxabar was the high cultist who completed the ritual but to his surprise nothing of what he expected came through the gate. Plague creatures, toxic gases and vapors, diseases of all kinds and decay lay quick waste to him and his cult. For some time the gate remained open and the settlements nearby were afflicted with diseases never seen before. The nearby town of Stagwood was quickly abandoned due to the plague. Rumor has it that the gods have weakened the gate and the cult has been destroyed. The remaining villages that managed to somewhat resist the plague are now hiring brave adventurers to venture into the tunnels and close the planar gate for good! Are you capable enough of surviving the horrors that reside in the Dreaded Tunnels of Ruxabar? Published by Mistfactor Press

A ten-part, fourthcore megadungeon designed to take a party of 4-6 players from level 1 to level 10. The Voice of All spoke three times before falling into silence. The first time to give shape to the Ancients. The second to give them the world as their domain. The third to build the TOWER for the war that was to come. And war did come. The Ancients, primordial warriors charged with protecting the world, were subverted by three great crusaders, vindictive and powerful. The Ancients were stripped of immortality and cast from the heavens to serve and suffer with the rest of humanity. The crusaders claimed new bodies for themselves, and became the Triumvirate, god-tyrants of all realms. The long line of descendants of the Ancients is dwindling, along with humanity’s last hope. What few remain have gathered to enter the TOWER OF THE ASCENDANTS. Crumbling stone tablets of ages forgotten say that a mortal who ascends the TOWER that pierces the heavens and slays the gods who dwell in its highest bower will reclaim lost immortality.

Written by the setting’s creator, incomparable RPG author Monte Cook, Ptolus: Queen of Lies is an action-packed fantasy adventure painstakingly re-designed for Ptolus: Monte Cook’s City by the Spire. Involving numerous challenging scenarios for characters of 11th level, Queen of Lies is filled with dozens of dark elf personalities, cunningly showcasing their alien culture—a world of merciless betrayal and sinister lusts. Deep below the surface, in the sunless lands of the Netherdeep, creatures of darkness build weapons and amass armies, dreaming of invasion. An attack on a peaceful elven shrine in Emerald Hill sends the heroes on a quest to retrieve stolen artifacts and kidnapped friends. All signs point to the actions of the dark elves of Ul-Drakkan, far below the city of Ptolus. However, even within that ancient fortress, there exists a deeper darkness.... Underground enemies lurk beyond every twisting passage, and strange creatures abound. The foul culture of the dark elves is both decadent and cruel, and the heroes may discover that they’ve stumbled into a web of deceit and treachery spun by the self-styled queen of the dark elves. Can the player characters complete their mission without being discovered, or will they find out, perhaps too late, that their actions been orchestrated all along by the wicked Queen of Lies?

The Tale of The Haunted Ravine is a Hex Crawl Adventure of Exploration that can be used for any game system but was designed for use with D&D 5e. A Hex crawl map and random roll tables are used to create surprising encounters and mysteries for your players to interact with. Wild necrotic magic, magical mutations, undead, lost souls, and demons all cloaked in a fog fog-choked landscape; forsaken by the gods and scarred by the battle fought here long ago. Will your adventurers survive and escape the Haunted Ravine? Or will they join the legions of cursed souls imprisoned in this corrupted land?

Introduction No frills, here. No fancy charts and tables. No art to dazzle your eyes. Just a crawl; that happens to have a bit of a background, and a (group)death-dealing Bad Ass! waiting for the characters. How you run it is your business. What you delete, exchange out/in or modify is up to you. You can be as kind and patient with the players as you like, or let the chips fall (dice roll) where they may. You can allow pre-rolled characters, provide pre-gens yourself, or let the players bring their own, favorite character they have worked hard to get to the levels indicated; remind them, if the latter, that character-death is part of the game! I issue only the following comment: if run as it is laid out , it is nearly certain that at least one character, and as many as all of them, might die during the adventure.

A millennium has passed since the Green Death swept across Hyperborea. In that bygone age of pestilence, a noble family fled the City-State of Khromarium. Far beyond the walls of the city, they entombed themselves in order to elude the inescapable plague. Their necromancer placed them in a deep slumber from which they never wakened. Also he summoned a mythical serpent to guard the vault, a beast reputed to shed gems for tears from eyeless sockets. Tales speak of this beast as the Sightless Serpent. Now, a knave of Khromarium claims to have witnessed the legendary beast. For a pittance he will lead your party to its trail in this swords and sorcery style adventure

This adventure has a lighter tone but isn’t completely out of place in a serious campaign. The challenges include combat, puzzles, traps and a legendary monster; Jack, in a Box. Does the party need to find something that an evil (and possibly mad) mage may have secluded away in an extra-dimensional space, and ordered an evil Jack-in-the-box and his toy army to protect it at all costs? Well that’s convenient because that is exactly the kind of situation that "Trapped in the Toybox" can help you with. Alternatively maybe that Dragon fight went a little too well for your party, maybe this “cursed chest” could help teach them a little humility. This adventure is designed for 4 (1d6 + 1) adventurers of 8th level who are in possession of a sense of humour. The toybox was created by a chaotic yet playful wizard, in order to hide an enchanted amulet under the protection of Jack. The adventurers should find themselves trapped inside the toybox, and they're in Jack's world now. Jack is the master of this domain and protector of both the amulet he has been entrusted with and the only exit of the toybox. There are a number of ways the adventurers may have come to be inside this toybox, e.g., the toybox may be found as part of the adventurer's loot in a dungeon or dragon's hoard, upon investigation it drags the adventurers inside. Note: This module commemorates our first themed week of Reddit's /r/Monsteraday and ties together this week's monsters in a dungeon designed for four 8th level adventurers. https://www.reddit.com/r/1d6Adventurers/comments/61axk3/trapped_in_the_toybox_adventure_module/ Published by 1d6Adventures

A centuries old evil has been cultivating an environmental disaster deep under the earth, waiting for the time when it will be unleashed on the world. A new mine has been created above and has broken the seal. The owner of the mine has lost contact with their foreman and shipments have stopped, and it’s up to an inexperienced but eager group of adventurers to investigate. This adventure is designed to present a challenge for a group of four veteran players using first level characters. While there are opportunities for roleplay scattered throughout, this adventure is heavy on the exploration and combat pillars of fifth edition. Death is a real and ever-present threat as they investigate the mine and the dangers below. Success and survival should bring them to the third level, and they may have found some treasure well worth the effort. So much so that they may become targets themselves from unscrupulous and more experienced NPCs. Written to be a seed for a larger campaign in any high fantasy setting, the outcome of this adventure could have world-changing consequences. It introduces a new and growing threat that, given enough encouragement, greed, time and apathy, could consume the world and beyond.
