"When I first came here, this was all swamp. Everyone said I was daft
to build a castle on a swamp, but I built it all the same, just to show them.
It sank into the swamp. So I built a second one. That sank into the swamp.
So I built a third. That burned down, fell over, then sank into the swamp.
But the fourth one stayed up. And that's what you're going to get, Lad,
the strongest castle in all of these lands." -- Lord WIllowshade
