An adventure in Hyperborea designed for from four to six characters of 6th through 8th level In the far reaches of Hyperborea’s Crab Archipelago lies a small, mountainous island known as Crystal Point. Passing sailors recently have witnessed a crimson glow in Crystal Point’s waters and beams of russet light shining up from its steep cliffs. Too, unusually frequent lightning storms in the area have torn the sky in blinding flashes, shattering the air with their awesome sound. The seedy wharf taverns of Khromarium and elsewhere buzz with these strange tales—some even speculate that Crystal Point may hold the lost treasure of Atlantis! The Lost Treasure of Atlantis takes players into an action-packed realm of adventure: the mythical world of Hyperborea, a sword-and-sorcery campaign setting inspired by the fantastic fiction of Robert E. Howard, H.P. Lovecraft, Clark Ashton Smith, and others. This adventure is designed for Astonishing Swordsmen & Sorcerers of Hyperborea™ (AS&SH™), a role-playing game descended from the original 1974 fantasy wargame and miniatures campaign rules as conceived by E. Gary Gygax and Dave Arneson. Therefore, AS&SH is compatible with most traditional fantasy role-playing games (c. 1974 to 1999) and their modern simulacra, such as OSRIC™ and Swords & Wizardry™.
