Something sinister lurks within an old elven siege fort…
Thirst for Knowledge is a Pathfinder adventure for 9th-level characters that slams together pulp sci-fi, fantasy, and horror in the tradition begun years ago with Expedition to the Barrier Peaks. Exploring a strange metallic cave, the heroes must rescue some lost dwarves from an alien priest of Cthulhu – but the knowledge they gain during the adventure might be even more dangerous.
Thirst for Knowledge serves as part three of the Ravenous Ruin adventure path from Wayward Rogues. With a little modification, it can also stand alone as its own adventure.
