A monster amonkst us... The monastery of Montelegro was once a major center of academia, but it fell out of favor when its library burned to the ground some 20 years ago. (The fire is rumored to have been started by the candle of a monk who fell asleep while reading.) Without books to attract scholars and patrons, the order of monks that run the monastery has dwindled. Now the monastery is a mere shell, its once-thriving halls empty. Only 21 monks remain. The order that runs Montelegro supports a number of scribes dedicated to copying and illuminating books of all kinds. The most talented of these illuminators was Brother Abel of Corbone, a young monk fresh out of the university. A few days prior to the adventure, Brother Abel witnessed a miraculous sight. While walking about on the outskirts of the monastery, he beheld a vision of his god. The vision instructed him to build a well upon the spot where he stood. If Abel did this, the god promised prosperity would return to Montelegro. Unfortunately Brother Abel was unable to fulfill his god's vision and appears to have taken his own life.... Or was there Murder in the Monastery? Pgs. 8-17 & 55

There have been disturbing signs over the last few months, signalling that something is wrong in Humblewood. The troubles appear to originate from activity in the Scorched Grove, an ashen plain that was ravaged many centuries ago by a destructive fire. Whatever caused the fire has scarred the land with elemental magic, making it inhospitable to all but strange fire-based creatures. Of late, the Grove has begun to expand. At first, it was hard to notice the slow expansion, but those in tune with nature (especially the Tenders) could see the imbalance in the elemental forces of Humblewood. For many common folk, this imbalance has been experienced as unseasonal dryness, which has led to crop failure and an increased frequency of forest fires. There have also been a number of unusually aggressive emberbat clouds reported far outside of their natural ranges. The true nature of the danger still remains hidden from the people of the Wood. A corvum necromancer named Odwald Ebonhart has stirred the elemental aspect of fire, which has lain dormant beneath the Scorched Grove since its first burning. The aspect’s energies have begun to empower fire-based creatures within the Wood. The increased range of emberbat swarms have brought fires that have expanded the Grove. Many forest-dwellers, who have been left without homes, have turned to banditry to survive. Soon the elemental incarnation will break free, and players must find a way to stop the aspect of fire before it reduces the Wood to ashes.

For the past several days, dozens of strong earthquakes have rocked the coastal area surrounding the underground Temple of Poseidon. Since the first quake, there have been a growing number of reports of strange events and macabre occurrences throughout the area. Several families near the temple have abandoned their farms and refused to return. They claim to have been terrorized by inhuman specters who prowled about their farms late at night. One of the farmers says he found a farm animal crucified and eviscerated in a ritualistic fashion on his front porch. Following the first tremors, all communications with the Temple of Poseidon, seemingly the center of the troubled area, were cut off. Messengers dispatched to the temple to request guidance from the Holy Oracle located there have not returned. Now the darkness has spread to this town. Unnatural births have occurred. Strange cries can be heard in the night, and there is a cowl around the moon. Magical divining has proven useless in naming the dark forces that invade. Many of the townspeople have already abandoned their homes and those who remain have but one recourse left: They have sent out a cry for hardened adventurers, experienced in dispatching evil. They must travel to the temple to discover the fate of the men there, and, if possible, elicit their help in destroying the growing heinous power. Pgs. 31-46

One crazy night in Waterdeep. Start as tavern bouncers. End up on the Astral Plane. All in one crazy night in Waterdeep. The party has been hired for a simple mission: make sure the Slumbering Prince tavern doesn't get wrecked during the rowdy Midsummer Festival. And what better motivation than 200gp per person for a single night of work. Sound too good to be true? Well, here's the catch: all damages to the tavern are to be deducted from that amount. And there is no shortage of festival-goers looking to unwind by wrecking other people's stuff. Over the course of the festival, the party must deal with drunken wizards, vain bards, loud goliaths, incompetent parade goers, complaining neighbours, disruptive satyrs, aspiring cultists, and a full-on tavern brawl. As well as an unusual number of strange slugs crawling around. Slowly they become aware there is something off about the Slumbering Prince. And when a reckless noble disturbs the secrets beneath the tavern, our heroes must soon delve into the hidden dungeon themselves. Down below, they discover the terrible threat: a planar rift that can only be opened on Midsummer's Eve, and the slumbering demigod that awaits beyond, the great astral slug Cthumbra!

Modrons, Mephits & Mayhem is a Dungeons & Dragons 5E tier 2 adventure for three to five characters of levels 5-8. It is primarily set in a modron-designed research facility that has been abandoned by its creators but retains guardians that are still active. Additionally, two groups have broken into the facility with their own goals in mind; the githyanki and their red dragon cohort are antagonistic and provide the main source of combat in this adventure, while a modron traveling with a few mephits may prove friendly although ultimately troublesome. Inspired by adventure games in which the protagonists explore baroque, esoteric technological fortresses, and seeded throughout with factions that sport competing and often bizarre goals, Modrons, Mephits & Mayhem is sure to test the mettle of any group of players, and will provide endless amusement for Dungeon Masters seeking something different from the typical hack-and-slash dungeon crawl. This 70-page adventure features: *Two wilderness areas, random wilderness encounters, and a massive, interlinking 3-level dungeon filled with bizarre puzzles. *Ancient machinery powered by elemental portals, all of which can be activated, turned off, or manipulated by the player characters and the various factions within the modron facility. *Planar creatures like githzerai and githyanki, modrons, mephits, and elemental guardians, skillfully placed into the High Moor area of the Forgotten Realms setting. *Monsters and NPCs that have detailed (yet easy to run!) personalities and goals that will provide tons of roleplaying opportunities. *Notes and sidebars on running the NPCs with added complexity, or simplifying the NPCs' motives to make the adventure more straightforward. *Tactics notes for every single encounter! *An appendix that features all monster stat blocks, and both tagged (DM) and untagged (Player) versions of the dungeon maps. *Wilderness hex map by Elven Tower Cartography! Three interlinked dungeon levels by Dyson Logos...and one of them is a flying fortress! Cover art by Patrick E. Pullen!

What the Diviners sense is the downed aeon starship Tähtihohde. Warred over by the ship’s inhabitants and assaulted by the Necromancer’s minions, the ship is controlled now by a clan of svartálfar who are attempting to repair the ship. Following the Diviner’s instructions, the PCs discover a curved metal trapdoor in the middle of the dark forest.
