A Pathfinder Roleplaying Game adventure for 10th-level characters, this volume of Pathfinder Adventure Path is part 4 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 13th level by the end of this adventure. “Blood for Blood” begins with the PCs having returned home from solving the mystery of the Varnhold Vanishing. Shortly after their arrival, they learn that new problems have developed during their absence—there are rumors of an army marching toward their nation!The PCs race to the village of Tatzlford, where they help defend the village from an attack by a small but earnest force of bandits, barbarians, and several lumbering trolls after being warned in advance by a troubled woman who has fled from Fort Drelev to the west. Following the skirmish, she pleads with the PCs to save her father and sister from peril.From there, the PCs strike out into the swamplands of the Slough to the west, exploring new lands and finding opportunities to make new allies and eliminate long-term threats to the region. Their initial goal, though, should be infiltrating Fort Drelev, where they’ll have a chance to confront the traitor Drelev with his crimes and rescue the Fort’s beleaguered settlers. During this time, the PCs learn where Armag’s tribe has been holding the daughters of Drelev’s senior officers hostage. Arriving at the ancient site, the PCs attack Armag’s barbarian encampment and overcome the sinister powers of the Black Sisters to free the girls. Then, entering the tomb, they face deadly traps, ancient undead horrors from a war-torn age, and the trials of the tomb’s immortal, divine guardian. In the final chamber, the PCs encounter Armag himself, armed with the ancient sword of his namesake.

She ran. Where to or for how long, she really couldn't say. The little flame of her oil lamp sputtered and went out a few times. She'd snap her fingers and make the wick flare to life, but she may as well have ran blind. The hallways were pitch black with soot and choked with smoke, every turn was a guess and every corridor a gamble. Unnatural screams echoed from every direction. Left, right, left again, was this the south or north end of the labyrinth? She had no idea. The next turn brought her face to face with a doorway completely consumed in blue fire. The room beyond was so bright she had to look through her fingers at it. A shadow covered her, a shape in the doorway: a hulking creature with a wolf-shaped muzzle and enormous pincers for hands, wreathed in the same blue flames. The screams were getting closer behind her, too. They had her cornered, again. The demon slammed its shoulders through the narrow opening, splintering the wood and stone. She dropped the lantern and let the wand in her sleeve fall into her waiting hand. With a word of power and a gesture, she appeared in the familiar bedroom: stuffy and reeking of wood smoke. She'd have to try again tomorrow, if she could remember. During an exploration on the sixth level of Undermountain, a strange invisible creature leads to a series of collapsed chambers that hide a forgotten secret and one of the most devastating forces known to the multiverse. Marambra Nyghtsteel, the forgotten apprentice of Halaster Blackcloak, has been locked away for an age deep within Undermountain. What point and purpose her forced seclusion has, only Blackcloak may know. When a spell consuming blue fire, known as The Spellplague is trapped within the chambers, a series of events have left Marambra, lost in her madness, struggling to survive.

Inspired by the "Happy Fun Ball" from the web series Critical Role, The Cube of Vanya is a magical adventure through demi-planes created by an ancient wizard, now destabilized by a malevolent dragon. The adventurers find themselves trapped within a series of themed planes with no idea how they got there. Navigating these planes to find a means of escape, they uncover the secrets of the cube while piecing back together their own memory. During the campaign the adventurers may fight shadow demons in an inn which is really a prison, flee a tornado while perched perilously in the sky, forge a weapon within a volcano, and much more. The module is structured in a non linear manner allowing the adventurers to choose their own way, or for the DM to pick and choose their favourite bits to highlight. The adventure was written with four level 5 players in mind but it would be easy to tweak for different sized groups around that level.

This book goes over the various rules around the faction of the Zhentarim in Phandalin and the Forgotten Realms, making it easy for any new or veteran DMs to integrate it more into the core stories being told, and making the faction feel more useful for the players that choose to join. The adventure, Barrhindlun sees the adventurers working for the Zhentarim and traveling to the town of Leilon and finding their way beneath to the muddy lost city of Barrhindlun, where bandits of the Xanathar Guild have been sent to reclaim a Crystal Orb.

"The screams became overpowered by the sound of the terrible falling star--a black orb of malign energy hurled from the firmament in the dead of night. In that instant, the village of Rhale was utterly destroyed, reduced to a hollow crater of flaming decay. Now, frightened talk of a dark presence descended from above has taken root, though none can put name to the faceless fear that might reside within this terrible orb." While traveling the countryside, the player characters witness an explosive event - the falling of a meteor into a distant hillside. Soon thereafter, they encounter several mercenaries menacing some refugees. From them, the PCs can learn, that a group of dragon worshippers called the Black Covenant are in the area and intend to use the fallen star for their own nefarious purposes. Upon arriving at the crater, the PCs find that the falling star is in fact a massive sphere of iron with an opening in its side. They enter the sphere to find a small complex of rooms protected by numerous traps and guardians. They also battle several members of the Black Covenant, until they make their way to the heart of the complex, where they discover the source of the Covenant's interest in the Black Egg, they try to use it to create a half-fiend red dragon. The PCs must succeed if they wish to prevent the creation of an army of fiendish dragons. Lot's of monstrous NPCs with class levels and templates for enemies (half-black dragon orc warriors level 7, for example) are used in this adventure. Pgs. 57-78

Life on the Moonsea isn't easy. Bandits, pirates, and cruel lords dominate the land, threatening those who make an honest living there. Now, a new scourge is prowling the waters: A ghost ship has been striking small coastal villages, leaving its victims whispering about the "eye of the dracolich."

A horrific drug has seized the population of the strange city of Exag, yet confronting its source only reveals the true extent of a dire new threat. Part one of the Seeds of Sehan campaign arc, this is a D&D adventure for 8th-level characters.

This adventure is the ninth part of the Shackled City Adventure Path that began with "Life's Bazaar" (Dungeon #97) Wherein a group of diverse and talented allies learns the folly of not working together against a common foe.
