This is Part 1 of an adventure designed for characters of the 20th to 21st level About 200 years ago a horrific massacre took place on the remote Soron island of Heikun. For months, the deranged and corrupt priests had sought to create a race of hybrid Snake-Men...a race which they believed once existed in Soro. They kidnapped folk from surrounding villages and took them back to their temple. There they performed unspeakable rites and experiments. Sensing their debasement, the dark spirits of the mountains called to the priests in their dreams, luring them down into the vast sub-levels beneath the Pyramid. Somewhere in the cavernous depths they were touched by an eternal evil and given horrific new forms. The deformed priest-things of Heikun crawled back to the surface, systematically destroying all living creatures in their path, including the city's hapless, ineffective leader: the inbred boy-king Yusef.

“The Temple Between” is an adventure for 9th level characters, and it is challenging enough to take them to 11th level by the time all is said and done. Although intended as the final chapter of the heroic tier portion of the Scales of War Adventure Path, it can be run as a standalone adventure, or as an adventure in a campaign of your own making, with a small degree of modification. It contains elements of urban investigation, dungeon delving, and even wartime conflict, making it a suitable adventure to players of many tastes and preferences. The western end of Elsir Vale has been greatly troubled in recent days. The threat of the orc hordes from beyond the Stonehome Mountains, though turned back at Bordrin’s Watch, still lingers in the people’s minds. Peculiar and hostile creatures of shadow lurk in the caverns and caves below. Political squabbling grows among the city’s powerful dwarf clans. All this makes the city particularly vulnerable to an enemy nobody saw coming - that nobody even imagined. This enemy has goals and objectives far beyond the ultimately unimportant Elsir Vale, but the first step is the utter subjugation of Overlook. An enemy who, at least in part, is already here. In this adventure the player characters start by investigating the strange behavior of the city's clergy. They swiftly discover hints of a conspiracy worming its way through the city hierarchy - some members are possessed while others have been replaced by dopplegangers. After trailing this conspiracy to its source they discover a portal that leads to an ancient temple in the mountains. Using the portal, the PCs go to the abandoned ancient temple where they must confront both a cadre of fey and a band of mercenaries, from whom they learn there is a plot for a full-scale invasion of the region! The PCs must them rush back to Overlook and cement their place as heroes as they face off against the invading forces. Pgs. 4-71

Long ago, before the arrival of civilized humanoids, a large colony of ogres thrived in the local area. When a great invasion from another dimension threatened this colony, their king, Koptila, prayed for his people to be spared. The gods heard these pleas, but commanded Koptila to sacrifice himself. The leader did so, and the clan disappeared—whisked away by the gods and lost to time. Over the years, a city grew up above the former subterranean home of the ogres, and no aspect of Koptila’s ancient bargain was preserved or remembered. Even so, the stars are aligned for the return of Koptila and his people. These powerful repatriates are unlikely to appreciate the changes in their old home.
