I built this kingdom up from nothing. When I started here, it was a swamp. Other kings said I was daft to build a castle on the swamp. But I built it all the same to show them. It sank into the swamp. So, I built a second one. That sank into the swamp. So, I built a third one. That burned down, fell over, then sank in the swamp. But the fourth one stayed up. And that's what you'll get, lad. The strongest castle in these isles.
The King of the Swamp Castle shows his son his kingdom and what he'll inherit some day.
