From time immemorial, the rulers of the mortal world have been counseled and tempted by capricious primordial spirits who rule over the elements.

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

Long ago, before the arrival of civilized humanoids, a large colony of ogres thrived in the local area. When a great invasion from another dimension threatened this colony, their king, Koptila, prayed for his people to be spared. The gods heard these pleas, but commanded Koptila to sacrifice himself. The leader did so, and the clan disappeared—whisked away by the gods and lost to time. Over the years, a city grew up above the former subterranean home of the ogres, and no aspect of Koptila’s ancient bargain was preserved or remembered. Even so, the stars are aligned for the return of Koptila and his people. These powerful repatriates are unlikely to appreciate the changes in their old home. A sage has found dusty documents prophesying this return, and he asks the PCs to investigate the catacombs to defeat the potential threat to the city.

Driven to madness by its secrets, he used the necromantic magic contained within to call forth an army of dread warriors from the Netherworld.

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.
