A centuries old evil has been cultivating an environmental disaster deep under the earth, waiting for the time when it will be unleashed on the world. A new mine has been created above and has broken the seal. The owner of the mine has lost contact with their foreman and shipments have stopped, and it’s up to an inexperienced but eager group of adventurers to investigate. This adventure is designed to present a challenge for a group of four veteran players using first level characters. While there are opportunities for roleplay scattered throughout, this adventure is heavy on the exploration and combat pillars of fifth edition. Death is a real and ever-present threat as they investigate the mine and the dangers below. Success and survival should bring them to the third level, and they may have found some treasure well worth the effort. So much so that they may become targets themselves from unscrupulous and more experienced NPCs. Written to be a seed for a larger campaign in any high fantasy setting, the outcome of this adventure could have world-changing consequences. It introduces a new and growing threat that, given enough encouragement, greed, time and apathy, could consume the world and beyond.

A Pathfinder Roleplaying Game adventure for 15th-level characters, this volume of Pathfinder Adventure Path is part 6 of 6 of the Kingmaker Adventure Path, in which the heroes win and defend a small kingdom from threats foreign and domestic. PCs should advance to 17th level by the end of this adventure. This adventure begins after the War of the River Kings has ended—the PCs, be they the war’s victors or losers, are faced with the task of rebuilding their kingdom or perhaps helping to rebuild Pitax. Yet soon after the war is over, a new peril strikes the region as strange monsters and violent bursts of rapid vegetation growth and bizarre weather plagues the Stolen Lands. At the same time, the PCs learn that one of the treasures discovered in Pitax’s House is a nascent vorpal sword, a weapon of immense power, and as the strange weather and blooms of life and monstrous incursions increase, so does this sword’s intelligence and power. The PCs soon learn that their kingdom faces an invasion, but this time not from the physical world. Some fell force from the legendary First World is attempting to expand into this world, and when the PCs begin to fight back against these verdant blooms, they discover that it’s possible to step from this world into the First World realm of Thousandbreaths. There, the PCs face powerful new threats unlike anything they’ve seen before, and learn that the dangers facing their kingdom are even greater than they feared, for the fey ruler of Thousandbreaths is about to absorb the Stolen Lands into a bauble for her own purposes, an act that would scour clean the region and leave behind nothing but a wasteland.If the PCs hope to save their new kingdom from this threat, they must combat the nymph queen Nyrissa both by stopping the various blooms in their kingdom and by traveling into Thousandbreaths itself to confront the dangerously insane nymph.

The last of his line, Baron Paytro NeMoren has left his dark secret sealed for decades in the family's underground vault. Now, years after his death, a group of stalwart heroes has gathered according to the baron's final wishes. At last, the seal will be broken and the secrets of the vault revealed. Can all sins be forgiven? The adventure is designed to kick-off a campaign, as it provides for an interesting way to get the party together. Instead of meeting at a tavern or being recruited by the local militia, each party member starts with a key to the NeMoren's vault, a key that was handed down by a friend or given as a gift for some good deed peformed in the past. The executor of the estate has gathered together all of the key-holders so that they could claim the contents of the vault. The vault can only be opened with all of the keys in unison. The vault is protected by a number of minor traps and tricks, but it also became the final resting place for the Baron's ex-lover, Lisette, and her brothers--all three of whom had attempted to blackmail the Baron. They were buried alive and are now undead. To complicate matters, a young umber hulk made its way to the vault, leaving some crude tunnels that were later exploited by hobgoblins coming from another surface entrance. The party will need to deal with the hobgoblins, the undead, the traps, and possibly the young umber hulk. There is a side-plot of poisoned groundwater in the nearby town that the party can also resolve by clearing out the undead and properly disposing of the putrid corpses leaking into the groundwater from the vault.

The module is designed to give novice Dungeon Masters experience fleshing out adventures and is only partially complete.

Part megadungeon, part underground expedition, Operation Unfathomable serves as both a one-shot adventure and a campaign framework. PCs are (optionally) drafted at swordpoint to recover the Nul Rod, a priceless artifact that was recently lost in a local prince's foolhardy attempt to destroy the Chaos Gods of the Underworld. The PCs have been drafted as an expendable set of pawns to venture into the vast and bewildering Underworld and retrieve the Nul Rod. With the Underworld's innumerable beasties being on high alert after the prince's expedition, the PCs must sneak through the incredibly dangerous Underworld. Fighting is not as important as stealth, fast-talking, and running away rapidly. This is the expansion from Sholtis's original Operation Unfathomable, released in Knockspell #5 (2011).

Prime Plane Immortals are dying like flies: nasty, violent deaths. The Hierarchs suspect Entropy, as usual, especially with all the rumors of demons' involvement. To top it all off, one of the Hierarchs is missing - Mazikeen. Your Mission as novice Temporals, should you choose to accept it, it to find Mazikeen, uncover his kidnaper, and bring him or her to a court of Immortal Justice. This entails much more than mere detective job - it also means taking part in the Immortal Olympics and going plane-hopping with the best (or worst?) of them. Should you not accept this mission, the fate of all Prime Plane Imoortals rests on your heads. (Well, it rests there anyway, but this is meant to make you more than a little guilty about not accepting - after all, you're supposed to be duty-bound and all that kind of thin, and I you don't do this, then who will? Huh? Did you ever think about that, Bucko?) TSR 9207
