From publisher blurb:
A Pathfinder Society Scenario designed for levels 7-11.
For millennia an order of scholars known as the Jeweled Sages catalogued the wisdom and lore of northern Garund's greatest minds within crystalline artifacts. Though these sage jewels have recently resurfaced, so too has the new generation of sages learned that something else dwells within besides ancient memories. The entire order gathers where the Jeweled Sages truly began in order to confront their hidden past, purge an ancient evil that has haunted them for ages, and define the future of the Scarab Sages faction.
Contents in Salvation of the Sages also contribute directly to the ongoing storyline of the Scarab Sages faction.
