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.

After escaping the oppressive rule of the hobgoblin empire, a tribe of goblins stumbles across a long-abandoned iron mine that would make the perfect home for them, if only it wasn’t already full of dangers. What lurks in the mine is however a secondary problem for the goblins, as they know that hobgoblin scouts will be hot on their heels. Looking to gain a valuable ally, they turn to the local town of Cathric for help. Under orders from the Marquess of Cathric, your band of adventurers is tasked with ensuring that the mine can provide a steady source of iron. Of course, this will mean helping the goblin tribe to get the mine working and defending them from their old masters. Your players will have to face off against the monsters in the mine, a hobgoblin scouting party and some over enthusiastic mining equipment, all while trying to put on a brave face in front of three trainee goblin fighters. Content warnings: spiders, enclosed spaces, displaced populations, authoritarian regimes. It is also implied that a monstrous creature is wounded by another monstrous creature.

This Digital Quarterly is built around a series of four micro-dungeons that can be used as an introduction to The Roslof Keep Campaign for characters just starting out. These dungeons should allow for a small group of players to not only become familiar with each other but also gain a level before taking up the banner of the Ivory Scimitar and entering Mithelvarn’s Labyrinth. As Roslof Keep is built around characters being asked to take up the Ivory Scimitar banner, it makes sense that they wouldn’t be completely ‘green’ and also might have gotten a bit of a reputation within Daern Kelton and Roslof Keep as trusted adventurers who are looking to help out the locals. This reputation can be used to bring The Folio: Digital Quarterly #6 the characters into the sights of House Aldenmier and, therefore, push characters into the campaign on a more realistic basis. It should also be noted that beginning Dungeon Level 1 with a level of experience is something that will be invaluable to the party and the early stages of the campaign. This adventure is formatted to both 1E & 5E gaming rules.

We get it. Factions are an integral part of D&D, but it's not always clear how to use them in your campaigns. Luckily, Factions of Sigil has you covered for each of the twelve main factions found across Sigil and the Outlands! This supplement goes over the various rules and lore around the primary factions found in Sigil and the Outlands, making it easy for any new or veteran DMs to integrate the factions more into the core stories being told, and making them feel more useful for the players that choose to join. In this adventure, the Heralds of Dust in Sigil ask the characters to investigate and end the disappearances in secret crypts under Sigil.

In this prelude to the full Princes of the Apocalypse campaign book, adventurers face off against the influence of Elemental Cultists in the hills and canyons of the Dessarin Valley. The four mini-adventures within are only tangentially related to each-other, and instead serve as starting points and hooks for the plots of the complete Princes of the Apocalypse Campaign. Players start in the well-described town of Red Larch; first investigating a local necromancer, then uncovering cult influences within the town, and finally heading off to infiltrate or do battle with two small elemental cultist strongholds. All parts of this adventure can serve as great places to seed hooks for other campaigns.

Stories of misfortune are often exaggerated, especially when they have been retold many times. For that reason, most people aren't taking seriously the claim that a sea monster living along the coast is eating whole ships full of sailors and swallowing entire families. But there's no denying a few facts -- the town of Lochfell is losing its citizens to a sea monster (one that walks on water no less), someone is stealing that same town's dead, and ships are beginning to choose other ports for unloading their goods. Such a scenario could doom the residents of the small port town to either a monster's gullet or the poorhouse. No one seems to know whether the town's two ongoing problems are connected, but the sea monster never leaves behind a corpse to bury. Is it collecting bodies for some dark purpose? Or did some more powerful evil creature create the sea monster to do its dirty work? Someone in Lochfell knows the answer, and it's up to the PCs to find it out. Lochfell’s Secret is a short D&D adventure for four 15th level player characters (PCs). The story is set in and around the port town of Lochfell. You can place the action in any section of your campaign world where a coastal town on a bay might exist. If there is a small town that the PCs visited in a past adventure but haven’t returned to in quite a while, so much the better. As always, feel free to adapt the material presented here as you see fit to make it work with your campaign.
