In the corner of an island, near the Brink of Sudden Death, is a castle. It's imposing, actually, standing partially embedded in a mountain and situated behind some horrifying walls.
The grounds are, as with all castles, expansive and clearly taken care of expertly, though these ones are… perhaps niche in appeal, with – instead of grass – a plant not found anywhere else on the surface covering most of the area not paved with burnt brick. With fires burning at the top of each turret, and blackened walls giving off a feeling of doom, one can tell this is not just a normal castle.
In fact, so the stories go, there is a horrible fiend dwelling within its walls, sitting on his throne of gold and laughing dreadfully as his minions go out to terrorize the local people, ordering that the skulls of the innocent be collected and displayed to show his might.
From time to time, the stories continue, a hero might evade the great forces laying waste to the areas around the castle, and might find themselves face-to-face with the Demon Lord.
But always, without fail, the stories end.
And the Demon Lord remains in his castle, and his minions continue his reign of terror.
