From publisher blurb: In ages past, a tiefling witch sequestered herself within a trap-laden tomb to acquire immortality for herself and her daughter. The witch must have failed, for her tomb has been sealed behind a serpent-shaped lock since that day. A clever adventurer found a way into the tomb centuries ago, but was never seen again. Now, her key has fallen into the hands of a descendant, who commissions the heroes to breach the ancient tomb and recover the adventurer’s remains. But this is no mere dungeon crawl; the heroes must overcome devious traps, intricate puzzles, a village of wary lizardfolk, and ancient betrayals to unearth a lost legacy. "Beyond the Serpentine Lock" is a wilderness and dungeon adventure for 3rd-level Pathfinder Second Edition characters.
