In times ancient, an infamous paladin-artificer named Khaldun unearthed a cursed tome bound in the flesh of the first medusa. Driven to madness by its secrets, he used the necromantic magic contained within to call forth an army of dread warriors from the Netherworld. Though his assault was devastating, he was ultimately unsuccessful, and the mightiest crusaders of the realm banished Khaldun to the Netherworld, where he would rot for eternity at the bottom of the River Dis. Unfortunately, rather than perishing in that bleak plane, Khaldun escaped his silt grave and thrived, amassing a legion of undead followers and erecting a Tomb in which he could perfect his mechanical craft without interruption. It was not long before he shed his body and became a demilich. After several centuries of scheming, the undead warriors under the command of the ‘Iron Lich’ have burst free of the Netherworld, laying waste to not only the mortal kingdoms that exiled him, but also the exalted domains of the gods themselves. The crusaders’ quest is simple – stead the Tomb and destroy the Iron Lich. Published by Defy Danger and Save Versus Death

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 hobgoblins were not the only forces that remained after Kalarel was slain. Before the Keep’s portal was fully sealed, evil spirits from the Shadowfell escaped into the Nentir Vale. They were drawn to Kalarel’s own dark soul, which remained in the mortal world thanks to a spirit-orb the priest had created to prevent him from moving on after death. The presence of these malignant spirits caught the attention of a frost witch called the Rime Mistress and her followers—unaligned territorial beasts—who rose up to defend their domain. The Rime Mistress knows that the spirits present a greater threat than the hobgoblins do, so she and Prang, the Iron Gauntlet leader, have agreed to an uneasy truce. Thus, the hobgoblins and the creatures of the Cairngorm Peaks are united in their struggle against Kalarel’s spirit army.

This is Part 1 of an adventure designed for characters of the 20th to 21st level About 200 years ago a horrific massacre took place on the remote Soron island of Heikun. For months, the deranged and corrupt priests had sought to create a race of hybrid Snake-Men...a race which they believed once existed in Soro. They kidnapped folk from surrounding villages and took them back to their temple. There they performed unspeakable rites and experiments. Sensing their debasement, the dark spirits of the mountains called to the priests in their dreams, luring them down into the vast sub-levels beneath the Pyramid. Somewhere in the cavernous depths they were touched by an eternal evil and given horrific new forms. The deformed priest-things of Heikun crawled back to the surface, systematically destroying all living creatures in their path, including the city's hapless, ineffective leader: the inbred boy-king Yusef.

Centuries ago, the four deities worshipped by mortals – Kishar, Kotaresh, Lyth, and Asar-Segt – threatened to drown the world in a flood of saltwater to punish the living for their impiety. The oracles and witches of the realm struck a desperate bargain with the gods, however, and convinced them to spare the world. In exchange, the mortal kingdoms were bound to demonstrate their faith once every generation by sending their most courageous and adroit warriors to the Crucible, a ziggurat in the lowest valley of the land. Every quarter-century, on the first full moon of summer, an eclipse darkens the night and the sealed ziggurat opens. Many traps, tricks, and guardians lie within the Crucible to test those who enter. Few who heed the challenge of the gods survive – most find only quick death. If the races of the world are deserving of the gods’ affection, their champions will overcome the trials of the Crucible and light the Divine Brazier hidden in its uppermost chamber. If they are not, the flickering candle of civilization will be snuffed. Little of value will have been lost. Published by Defy Danger and Save Versus Death
