Note: This is a sequel to Out of Body, Out of Mind. The legend of the realm of Tirna'cel is well known. Once remembered for its power-mongering warlords, homunculi-wielding sorcerers, and archfiends from the deepest pits of the Abyss, Tirna'cel has become a powerful and welcoming land over the last 600 years, due in no small part to the efforts of the warlord Tirna'gael, a member of the land's founding nobility. But your party knows the truth. You ventured into the tomb of Tirna'gael some six months ago, and therein discovered that the fallen warlord was actually little more than his brethren: a petty, avaricious power-monger. Possessed by a rival force which also desired the kingdom - a rare incorporeal demon called a nescent, which inhabited his body and augmented his already incredible power to unforeseen levels - Tirna'gael sought to overthrow the ancient warlords only to replace them. Through Tirna'gael's augmented body, the nescent overwhelmed and eliminated the other warlords, eventually dominating the realm along. But before it could consolidate its rule and throw Tirna'cel into an even darker age, the secret of its power was discovered by the paladins of Garadon, a virtuous cell of justice and light. The paladins lured Tirna'gael into the center of his own fortress and trapped him there within a powerful anti magic field. His body withered and died but the nescent remained dormant, waiting for its chance for revenge. During your visit to Tirna'gael's fortress-tomb six months ago, you accidentally released the nescent from its prison. That enemy has since been vanquished - at least for the time being - but the memory of your pitched battle against it still lingers as you approach the original chapter house of the Order of Garadon. You have been summoned.

Lowharbor’s residents vanish when they die. A cloud of sour black smoke chokes their corpses and, when it clears, all that remains is a dusting of salt. Something or someone is stealing bodies through magic ritual, and the townsfolk won't stand for it! Send your party into the dank sewers below their feet to root out the necromancer's den of swirling filth! Why should you get this module? Skulking horrors and excitable clerics! Seven brand new monsters, including a low level mythic statblock! New disease rules! A mysterious threat! Six hours of play! Lavish presentation! A fantastic adventure for 5th-level players! Dead Ends is best for 5th-level players. It might be a little tough, but still winnable, for 4th-level, and should be fine for anything up to 8th-level.

Base of Operations is a short adventure intended for four 5th-level characters. DMs can easily modify the adventure to suit higher- or lower-level adventurers, or larger or smaller parties of adventurers. Simply adding a few monsters to every encounter area makes the adventure more challenging for larger parties, and adding levels to any of the humanoids can make them more of a threat to high-level groups. For low-level adventurers, make the relationship between the two factions within Brightstone Keep more strained, and take away a few monsters from each group. You can remove levels from some of the humanoids in the adventure to make it a lower-level challenge, but it is important that the orc cleric (described in encounter area 8) still have the ability to animate the dead. Still, he can have fewer minions around him when encountered, and that makes him less of a challenge for a lowlevel party.

"The first raid on our village happened a little over 3 months ago. We awoke in the morning to discover that the Cooper family's house at the edge of town had been sacked in the entire family was missing," croaks Obed, the village elder. "We mounted a search party, but found no trace of them." The old man lifts his gaze to the west woods. "After the third such attack, we sent a messenger to seek aid from one of the larger towns nearby. He never returned." He turns back to face your party and continues, "We had no idea who or what was attacking our village... Until last week. Creatures in black robes drifted out of the woods to the west and began setting houses on fire. Then, they seized four of our bravest men and carried them, screaming, into the mists." Obed throws his mug of ale into the fire, suddenly angry, "The only creature capable of this evil is the Barrow King, who lives in the burial mounds to the west. But I swear, we have done nothing to focus his anger upon us, nothing!" Warily, the elder stands, leaning heavily on his walking stick. Slowly, he lifts it, pointing at each one of you in turn.

Many centuries ago, a band of paladins fell from grace. These blackguards were defeated after a great battle and their grim fortress, the Iron Tower, was razed. A small abbey was established near the ruins, where generations of monks mixed ancient eldritch wards, mighty clockwork traps, and multiple fail safes to build the Iron Crypt of the Heretics. Three mighty vaults ensured that its evils would be sealed for all eternity. But unbeknownst to the brotherhood, their impregnable crypt had a single weakness: the very monks that had built it, for they knew its secrets. When a devourer stole into their abbey, the profane beast forced the monks to help it inside the Iron Crypt. It successfully broke into the first of three vaults, releasing an army of wights. The story of the devourer and his wight army is told in Dungeon Crawl Classics #12: The Blackguard’s Revenge. Now, in the Iron Crypt of the Heretics, the heroes must venture into a crypt designed by the world’s greatest thieves, magicians, and seers, solve its puzzles and deadly traps, and seal it once more from the outside world.

The secret of this tomb's location has been passed among a select few people as the years have gone on. Most of the general public do not even believe it exists, but now the ancient relic buried alongside Dromar is needed once again.
