The Dark Cathedral was once planned to be the most impressive cathedral of all time. But due to an enormous earthquake it has been destroyed. The ruins are cursed and anybody who dares to go there might not return to the surface. All those that travel there leave the place with bad luck for the rest of their life. Crumbling structures might fall upon the adventurer who can then not escape. Those who survive the dangers of nature will face the soul-eating ghosts of those who have died in the catastrophe.
According to Lorbas, there are no riches or treasures left in the ruins, the gold of his order melted away in funding the cathedral's construction...
The Dark Cathedral is located south of the Outlaw Camp, and west of the dreaded Plains of Havoc, and can only be reached by crossing the big plains, south of the swamp of Venore.
