Beyond the haunted swamps of western Golnir rises the grim fortress of Slank — the arch-fiend who has stolen the souls of mortals for centuries. Now the secret magic to destroy him is known, and your journey into the Castle of Lost Souls begins. Will you break his hold over the dead… or join them?

Based on the newly rewritten 700-section adventure by Dave Morris & Paul Gresty, this DLC brings one of the most iconic Fabled Lands quests into the CRPG with new locations, enemies, mechanics, and treasures.
A Dark Quest Awaits
Venture across cursed marshes, ruined villages, and the demon’s stronghold itself. Descend into the underworld, uncover forbidden rituals, battle corrupted spirits and undead guardians, and gather the tools needed to challenge Slank at the heart of his domain.
