Duluum is a swampy mess in the northwest of Traleaux. It is bordered on the west by the sea, on the north by Solafeth, on the east by Wondimu, and on the south by Muftigowen.
Duluum is mostly unexplored, at least from the perspective of anyone you have ever met. People occasionally wander into the swamp, but they rarely return.
Most of the residents of Duluum are non-sentient, but there are at least some Dragonborn living inside. Unless you have personally met one, you probably know very little about them.
The entire region is a marsh, with sporadic hills that climb out of the muck. There are no known settlements inside it.
Nothing is known about Dragonborn society.

There is effectively no trade between residents of Duluum and the outside world.
