Pathfinder Adventure Path Return of the Runelords #5 The City Outside of Time

Frozen in Time!  With the discovery that Runelord Alaznist has tampered with the past and set into motion devastating transformations of the timeline, the heroes must embark upon a truly dangerous and desperate gambit. Since historical texts and their own memories have been altered, the lore hidden within a time-trapped city may hold the only clues as to which events of the ancient past Alaznist has targeted. If the heroes can isolate these events, they may have a chance to correct them, but before they can even reach this repository of lore, they must brave a shadowy god's realm and find a way to enter a city that has been cut off from time itself!
