None know from where the Heresiarch first came, but all remember the night that it did. It rode down from the bleeding stars on a great serpent, hurling bolts of obsidian lightning that shattered the monuments and capitols of every nation. Its infernal army swept aside the defenses of the mortal empires in a single hour, decimating legions once thought to be the invincible fist of humanity's god-kings. Faceless priests - each bearing the symbol of the trident - drifted through the fallen cities and scorched villages on a frigid wind, and when they rose to greet the huddled men and women ringed by their festering, bloated dead, they spoke a single, simple offer: worship the Heresiarch or die. Thousands of crusaders fell tonight so that you might be given this chance. In a last stand that, for the first time, united all of the empires of humanity as brothers and sisters, a way was cleared into an infernal stronghold said to contain a gate to the Heresiarch’s fane. All is silent save for the clangor of distant battle. Surrounded by grim-faced knights and teary-eyed peasants – their hands clasped in desperate hope – you step through the glowing, churning doorway, knowing there will be no help and likely no return.

"The creatures are just too intelligent, too crafty, and too strategy-minded to "rampage." Rampaging brings the wrath of oath-bound knights, powerful mages, and divinely-protected priests. Why would a dragon want such attention, unless it had some special secret, or unless it was insane? Or both. The northern reaches of the Derideth Swamp were once plagued by a rampaging dragon. This black dragon, named Storamere, took a mad glee in attacking human villages, wiping out orc camps, driving off the lizardfolk, and decimating farmland. He met his untimely end, though, in an ambush devised by the monks of the Order of St. Chausle. Storamere died with a curse upon his draconic tongue: "you could not have defeated me in my lair," he told his slayers. "I am forever invincible in my lair." Now Storamere is back, with a horde of his misshapen half-dragon offspring, to have his vengeance. All that remains of the once-heroic monks are two old men driven mad by their last encounter with the black dragon, so it falls to a band of adventurers to again defeat the mighty dragon -- this time in his palace, where the boastful Storamere claims he is at his strongest." Includes maps and damage rules for navigating Storamere's lair, a semi-solid palace made of a dangerous, corrosive liquid five feet thick and located on the ethereal plane. Most of the monsters in the lair have the Half-Dragon template applied. Published by Atlas Games

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!
