Also known as the Castle on the Abyss, the Last Castle, and the Rooms of Ruin, this imposing fortress in End-World abuts the village of Fedic. Named for the great crack in the earth beyond it, filled with terrible monsters from the todash darkness. The castle contains long stone corridors floored with black and red marble, a vast Banqueting Hall, and crypts housing slo-trans engines built by North Central Positronics. From its Allure one can see southeast to the Forge of the Crimson King. It is the last castle before the Dark Tower itself.
