Finding a legendary tomb requires tracking an equally legendary cave
worm said to dwell there. As the adventurers set out from Highhelm, they
must brave the Darklands' dangers, navigate a treacherous fey city, and
recover the relic that retraces the cave worm's path. Yet in doing so,
they learn of nefarious rivals who also seek the tomb--rivals the
adventurers might stop by infiltrating an unforgiving underground
metropolis.
"Cult of the Cave Worm" is a Pathfinder adventure for four 5th-level
characters, continuing the Sky King's Tomb Adventure Path, a three-part
monthly campaign in which a group of adventurers travel deep underground
to discover a legendary dwarven king's tomb, seek subterranean
treasures, and heal millennia-old injustices--all while stopping an
ambitious villain from weaponizing those same discoveries. This
adventure also includes a study of cave worm ecology, a gazetteer of the
duergar city Hagegraf, potent relics, and several monsters to threaten
underground explorers.
Each monthly full-color softcover Pathfinder Adventure Path volume
contains an in-depth adventure scenario, stats for several new monsters,
and support articles meant to give Game Masters additional material to
expand their campaign. Pathfinder Adventure Path volumes use the Open
Game License and work with both the Pathfinder RPG and the world's
oldest fantasy RPG.
