Once every decade, the tides of the Empyrean Ocean recede far enough to reveal the highest eaves of a mysterious undersea tower. Long ago this was an eldritch fastness of Sezrekan the Elder, the most wicked wizard ever to plague the Known World, but now the tower is known simply as the final resting place of the fabled Black Pearl – an artifact rumored to bring doom upon all who dare to posses it. Tonight the moon nearly fills the sky, and the tides have already begun to recede. Adventurers have eight short hours to explore the tower before the dark waters return. The fabled Black Pearl will be theirs for the taking…if they can survive the Pearl’s curse.

Deicide is a campaign designed to begin with a party of four to six 1st-level characters, who should advance to 20th level by its conclusion. The Gods have abandoned Faerûn. Bringing loved ones back from the dead hasn’t been done in centuries, and communion with the deities is a spiritual exercise only. Holy warriors and messengers have lost their powers and have all but completely disappeared. In this bleak world, wars are frequent, crime runs rampant, and hope has faded. Rumours are abound of a mysterious crime lord taking control of the underworld. Monsters roam the lands and every road is increasingly more dangerous. Without guidance, the many civilizations of this world are plagued by greed and corruption. The only way forward is to bring the Gods back, or to take their place in the heavens. Deicide takes place across two islands, Aurora and Limdorkal. These landmasses are the westernmost islands of the Moonshae Isles, an archipelago located roughly 400 miles west of the region of Amn and to the southwest of the Sword Coast. Surrounding the Sea of Moonshae, these islands feature a wide array of cities, civilizations, climates, terrains, and monsters. Limdorkal is famously a harsher environment, home to exotic races, whereas Aurora is almost entirely dominated by the human kingdom. Elminster Aumar, the famous Old Mage of Faerûn, once visited these islands and claimed it surprising how such diverse environmental systems erupted here, and how varied were the people inhabiting them. While the Sword Coast is part of Faerûn, a continent of Toril in the Forgotten Realms, feel free to adapt these islands to any setting of your choice, such as Ravenloft, Eberron, Ravnica, or even on your homebrew world. The story told here happens some hundreds of years after the beginning of 5th Edition, and the Overgod Ao is trapped inside an artifact, which limits the workings of gods around Toril. The characters will be able to learn more about the missing Gods, about a mythical folklore artifact known as the Wand of Wonders, which carries the powers of the Gods, and about the crime lord Kaiser Soze. Through their adventures, they will be able to visit other realms, planes, and dimensions, as well as come into contact with different races and civilizations. In the end, it is up to them whether to ally with the Crime Lord, and whether to release the Gods or keep their power for themselves. This campaign can work as a loose set of modular adventures, which can be easily picked separately and played as one-shots of different levels. Even their locations on the map might be moved, and events happening in particular towns can happen on others. The adventures include dungeon crawls, murder mysteries, sandbox urban quests, exploration on land and in the seas, inter-planar travelling, among others.
