Stats for both BECMI and 5th edition, and setting neutral (though there are some implied things about the history of the world).

In these lands of eldritch goo, it's a fine line between victory and a sticky situation Tzork, the sentient globe of glass, wasn’t exactly born from a grand spell—it was more of a cosmic "oops". After a backstabbing disciple named Theridus offed his master and snagged the relic, he promised his followers unimaginable power. But instead of turning them into terrifying demons, Tzork turned them into puddles of goo. Now, the once "glorious" cult's mansion is less a temple and more a swamp of melted, failed adventurers, attracting only the most reckless of treasure hunters. 'Morass of the Melting Men' is an adventure for Knave 2e, suitable for low-level PCs. The adventure revolves around an extremely powerful sentient magical item that has gone out of control, melting all the nearby people and turning what was once an evil temple into a swamp of slime, filled with bones and eyeballs. In Morass of the Melting Men, players enter a location flooded with a magical liquid exuding chaotic energy. The longer the PCs remain within the swamp, the more they suffer the unexpected effects of this alien magic. Step inside this morass if you dare — goo and treasure awaits... but mostly goo What you'll find here: A complete 40-page adventure A 20 room dungeon map Several new (and bizarre) magic items such as the magnificent Tray of Force and the powerful Theridus' Head.

Your party approaches a barrow at the base of the mountain. A raging storm brews overhead, and as you approach, a bolt of lightning strikes down on the peak of the mound, lighting up the world all around you. A thunderclap momentarily deafens you, and as your eyes adjust to the resuming grey of the dark day, you see a flicker of firelight emerging from the two gaping holes built into the side of the hill. You’ve found the pirates camping within the Barrow of the Raging Storm. As I delivered it to my players, the premise of this Midnight Sun adventure is that some pirates have been attacking ships returning from raids. They have been stealing the loot and the corpses of any slain Nords. Among their victims, a ship from Valthis returns to tell them that the pirates sailed upriver (to hex 506), where I placed the Barrow in my Shadowdark RPG campaign. The adventurers started from there and explored the dungeon thoroughly. The adventure was created using the tools described in the Shadowdark RPG core rules. I created it in about 6 hours between 2024-03-08 and 2024-03-09 and ran it for my group on the 9th. It took about 2.25 hours to play to completion. The party consisted of two level 1 characters and one level 2 character. I had so much fun making and running this that I will continue creating more Midnight Sun Adventures, so stay tuned!

"Something is weird about this party in 16th century Scotland! A famous thief stole a magical jewel and hid inside a castle where a party is taking place. Enter the party, find the jewel, escape with your life. In the first half of the adventure, the player characters will explore a weird party in search of the thief Jougal. They’ll likely piece together that this party is not “normal” and that this castle is not safe. In the second half, the baobhan sith will reveal themselves, red caps will set the castle on fire, and the PCs will find themselves locked in a burning hellhole. The adventure will likely change from a fun party-crawl into a stressful fight for survival. This is the NIGHTMARE PHASE." This adventure blends elements of horror, survival, and mystery, requiring players to use both their combat skills and their wits to navigate through the treacherous and evolving scenarios within Firnhirst Castle.
