Kesnar
From DALpedia
Kesnar is the only port town on the island nation of Tjed. The port itself is very extensive and quite advanced, as Tjed's flagship, the Posidon X is launched from here and can be seen diving under the waters, not surfacing again until it is next needed.
The town is surrounded by beautiful mountains scenery, as is most the rest of Tjed. There is a small obscure tunnel through the mountain directly to the north that leads to Tjed's capital city, Tjedon, among other places and some dead ends, as it is a quite confusing passage. The tunnel was built this way to ward off would be invaders, and only locals who are familiar with it can navigate it easily.
