Called by the Elder Elemental Eye to serve, four corrupt prophets have risen from the depths of anonymity to claim mighty weapons with direct links to the power of the elemental princes. Each of these prophets has assembled a cadre of cultists and creatures to serve them in the construction of four elemental temples of lethal design. It is up to adventurers from heroic factions such as the Emerald Enclave and the Order of the Gauntlet to discover where the true power of each prophet lay, and dismantle it before it comes boiling up to obliterate the Realms.

The heroes arrive at the eponymous Keep on the Borderlands, a fortress on the edge of civilization built to stave off the chaos and evil of the wilderness. Using it as a home base, a party can make forays into the surrounding wilderness, encountering monster and marauder alike. The centerpiece of the adventure is certainly the CAVES OF CHAOS, a network of tunnels and caverns found in the walls of a nearby but isolated ravine. It is here that hordes of evil humanoids have made their home. Through combat and negotiation, the players can try to explore and map out these caves, perhaps with the aim of accumulating valuable treasure or even cleansing the land of evil creatures. However, even the Caves are not all they seem. Beyond the goblins and kobolds lurk dark horrors: cults dedicated to fiendish chaos and a Minotaur's enchanted labyrinth await the unprepared adventurer. But for the hero who is brave, clever, and fortunate in equal and sufficient measure, great treasures and glory await in the Caves of Chaos that lie beyond the Keep on the Borderlands! TSR 9034

A sequel to the Lost Mine of Phandelver adventure for 5th and 6th level characters. An ancient forgotten evil threatens the Sword Coast once again! Our party of intrepid adventurers returns to Phandalin and Wave Echo Cave for what is at first glance a rescue and exploration mission. Prospectors for the Rockseeker mining concern have disappeared deep inside the flooded caverns that give the cave its name. The peril extends much deeper than mere lost explorers though, as the party stumbles upon an ancient, long-forgotten struggle between good and evil. Inexplicable cultists hide in ambush at every turn. A risky raft ride through treacherous underground waterways leads to an ominous discovery. Ancient ruins tell a story of the terrors of the night and a noble alliance sworn to fight them. A search for a powerful weapon of light leads the party on a mind-blowing, sky-high ascent into the unknown. Then, a whirlwind of danger: A rumbling volcano. Legions of undead. A desperate battle for the survival of the region. This adventure was designed as part of “The Next Adventure” Design Jam at the DMs Guild. It works best for a party that has just completed the Lost Mine of Phandelver adventure, but it can easily be inserted into any campaign. It is designed for a party of four to six 5th or 6th level characters and, based on playtesting, will take an average of about 3 sessions to complete.

Dragonbowl is a setting and pulp action adventure in one. It plunges a party into a rich festival scenario that revolves around a deadly gladiatorial contest, where the dangers they face in the arena are almost secondary to those they encounter in the murky criminal underworld they find themselves in: a world that stinks of corruption, human trafficking, illegal dinosaur-trading, necromancy, blood sacrifice and unnatural arcane experiments. The action takes place in a vast cavern in Mount Waterdeep, known as the Underbelly, where not only Dragonbowl Arena, but also an entire festival grounds – consisting of temples, bars, casinos, funfairs and markets - has been constructed to host this grand sporting extravaganza. With Xanathar, Jarlaxle, Davil, Volo and the Black Viper all in attendance, and scores of 'entanglements' (faction missions) to keep players busy, Dragonbowl can be played as a sequel to Waterdeep: Dragon Heist, or as a first step towards the Undermountain and the Dungeon of the Mad Mage. Equally, it can be played as a stand alone adventure, or easily transported into other settings. The adventure is written for a party of four 6th level adventurers, and easily customisable for three to five players, of any mid-tier level (the adventure contains maps and handouts adapted for both 4 and 5 player tables). The adventure is designed to last around ten to fifteen 4-hour sessions, but can very easily be shortened or lengthened according to the DM's desire. The adventure features all three pillars of play: combat (in and out of the arena), social interaction (a succession of parties and parades, where players can get entangled in NPC business) and exploration (30+ locations in the festival grounds alone).

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.
