The Northern Desert are few in this portion of the map, with them being heavily outweighed by woodland and grassland, in particular the Mega Taiga and Swamplands.
The deserts all have access to the sea, providing access by a move-craft boats, they are also often terraformed, or have large builds upon them, due to the fact the deserts are often an annoying biome to find yourself settling in. There are 2 deserts biomes who can be accessed by the landlocked Northern Sea, there are fragmented desert biomes to the west of these in the next sea, and the largest desert in the North is at the top of the map, it's access is much more restricted, but this has not discouraged settlers.
