Here's my rework, or second version, this time with a legend:
map v2
legend v2
Again, east is the upside of the map, as the sun rises in the east and drops in the west.
This means the cold north is left on the map, the tropical south on the right side.
The type of map might provoke misunderstandings, like, there's no wood in the mountains or hills or swamps. Of course there can be.
I thought of a way to show both height differences and vegetation types in the same area and concluded it got rather complex to the eye.
I deliberately drew no borders. Now it is open wether the mountain faction will occupy a bit of wood e.g.
Only the rough centers of the four factions are indicated.
There's no white, which doesn't mean all terrain is occupied. It's just that the map hasn't unknown terrain types.
All four area's have a coastline. It's open to the game/lore if the ice sea, sunny sea and western sea are connected.
All four area's have the possibility to extend over land beyond the map's borders.
I thought it fun to have an isle in a lake in the heart of the continent. Again, it's open who owns it.
It might be the high king of all. Or any faction. Or the holy grail. Or just animals and flowers.
There are several types of coastline. Fjordlike in the north, islands in the south east, beachy in the south, I imagined lower cliffs in the south west, a muddy swampy delta, and two steep canyons between isolated pieces of mountain in the northwest.
The mysty isle has a variety of terrain types and has got a lagoon.
I thought it important to map the great rivers, as they are barriers and means of transport at the same time.
The 'alto plano', barren high but flat land, seemed an interesting terrain. This part of the map grew a bit dull without something unusual. Now that I look at it again, I realize this part of the continent could have used a few big lakes, as there are hardly rivers. Maybe a version 3?
Have fun with it, as I did drawing the thing.
