Cross the Silent Expanse—154 square miles of psion-scoured desert—and brave mounting psychic hazards on a five-act trek to Karak-Tor’s half-buried pyramid. Hired by Jaeson Strone and guided by his grim son Corinis, the party endures whispers, visions, scavengers, and mind-born predators while a “Blind Merchant” returns again and again with suspicious protections. At the threshold, the Caretaker reveals himself—the last sentinel who denies the unworthy; defeat him, shatter the crackling capstone, and descend into sealed chambers where relics hum, energy leeches feed, and loyalties tighten around the vault’s secrets. Designed for four 7th-level characters (8–12 hours, Hard), Desolation of Karak-Tor features unique monsters, memorable NPCs, environmental pressure rules, tactical set pieces, and a trove of psionic-era artifacts.
