With one imminent apocalypse prevented, the heroes can finally focus on directly opposing the machinations of Runelord Xanderghul, whose pursuit of revenge continues to threaten the Saga Lands—and Golarion as a whole! But to reach him and force that confrontation, the heroes must risk it all in conjuring a personification of doomsday known as the Oliphant, for this titanic legend is their only pathway into the deadly realm where Xanderghul awaits: the Apocalypse Archive of Jandelay!

Into the Apocalypse Archive is a Pathfinder adventure for four 18th-level mythic characters. This adventure concludes the Revenge of the Runelords Adventure Path, a three-part monthly campaign in which a group of adventurers fight against the evil plans of Runelord Xanderghul—the most powerful of all runelords. This adventure also includes rules for large-scale apocalyptic disasters and presents a range of legendary artifacts and monsters to reward and challenge high-level characters.
