Is there no way to separate the ground water level and sea level currently? I ask this because I have seen occasional turret like structures with spiral stairs descending into the swamps and wonder if they will be some future content within the swamp (some kind of buried castle-like dungeon maybe?)

I am aware that a lot of valheim's map is procedural generation; in the swamp I often see small pieces of land that look like mounds. Would it be possible that mudpiles would more likely be spawned under those than other lower landmasses?

I am hoping to keep this as a pleasant chat about possibilities and ideas (which is my intention here).
