Wicked forces conspire to usurp the power of the Raven Queen, god of death, by unraveling the foundations of reality. To prevent this cosmic coup, mighty heroes must survive an epic journey into the Shadowfell's timeless core, where all things find their end. The beginning of the end of the original 4th edition adventure path (although ties are very light to the heroic and elite tier adventures). The PCs must first prove themselves worthy to act as the Raven Queen's agents. They will then be sent to Death's Reach, a graveyard and dumping ground from the Dawn's War. There, they must fight through the Black Star Host- powerful elemental beings, to prevent Orcus was resurrecting a primordial, Timesus the Black Star. One notable encounter is a random encounter with the Worm of Ages. This huge worm has the ability to swallow and rules for moving creatures from its maw to its throat, gullet, and into the stomach.
The Thrice-Damned House of Thrune wants to seal the Inferno Gate, an uncontrolled portal to Hell, and the villainous adventurers are called to accomplish the task. To acquire the components and perform the ritual, they must first face down a hellspawn thieves' guild, the Hellknight Order of the Pike, and the knights of the Glorious Reclamation and their celestial allies. But before they can complete the ritual, the characters may be forced to examine their options—is closing the gate the best plan for the future? Will the villains obey their orders to close the gate to Hell—or might they make a deal with a devil for control of the portal? Or will they only become the latest in a long line of sacrifices to the Inferno Gate?
In order to rescue a friend, the PCs must sail into the Abyss and infiltrate a prison built by the Prince of Demons. A Savage Tide Adventure Path scenario.
