Deity: Dispater, Lord of those Below
No Kings Beyond Death
A god of riches and horrors beneath the earth, protector and jailer of the departed souls, grim Dispater rules many realms with a stern hand and an iron will. Often cursed and seldom praised by mortals, it is this god's cosmic lot to keep order in the underworld, where the caverns of the mortal plane intersect with the labyrinths of the underdark and the shadowed halls of the dead.
While his worship overlaps with many other gods of death, few pray to Dispater as his heart is thought to be as cold and unmoving as stone, hardened by the grim work of keeping the domains to which psycopomps and other terminal forces deliver souls, ensuring that they neither have the chance to escape nor that they are picked off by fiends or other malign spirits.
Judges and other arbiters sometimes swear by him, especially when handling matters of life and death, as do miners, bankers, and others who work in precious metals or stones, as Dispater has a connection to caverns and other buried places. His clergy collects tribute in the form of those soft, perishable things that cannot be found below the earth: grain and livestock, flowers and wine. Their sacrifices of these things are said to pass on to the dead themselves, after their lord has taken his due tithe.
Adventure Hooks:
A monstrous bat haunts the countryside, endlessly harrying a graverobber who pilfered from a cemetery consecrated in Dispater's name. The exhausted scoundrel just so happens to have taken refuge in the same country inn as the party, passing himself off as a peddler who was shaken down by bandits. When the bat attacks that night (as he knows it will) he hopes to use the chaos to shift some of his plunder into the heroes' packs, diverting the creature and the divine wrath it represents.
Rumour is, if you find a trail of archaic coins scattered along the road, following it will lead you to one of the mysterious grey merchants, traders from the underworld who deal in memories and mementos cast off by the dead. Woe to anyone who attempts to harry or cheat the merchant though, as they travel under the protection of the lord below.
Shortly after a resurrection of a partymember (that may or may not have gone wrong), the heroes are approached by a dour devil in clerk's garb who insists that they need to follow her into the underworld to help clear up some post-mortality paperwork, or else their friend's soul might be held in litigation for a literal eternity. "Clearing up" in this case involves helping to clear out a field office somewhere in the shadowfell overtaken by the unquiet dead, fending off hostile spirits while the devil and the deceased do a lightninground of signatures on the relevant forms.
