This map shows the relationship of the land-forms shown in the maps below; they've been overlaid on the basic map. There is minimal geopolitical detail shown. Each hex is 1,000 miles across, from side to side.
The yellow circle shows the path of the sun and moon — they are on opposite sides of that circumference.
"North" is the centre of the plane, "South" is the perimeter, so it is not necessarily a constant direction from two different places on the plane.
It's important to bear in mind that this world IS NOT A SPHERE. It's a flat(tish) plane.
This is just one of about twenty or thirty adjoining planes on the surface of a multi-planar sphere. If you imagine a d20 or d30, this would be one face of the die. With the proper protection and life-support, it is possible to walk from one "face" to another (though border conditions are inimicable, to say the least), and the planes also interconnect via the UnderDark.
The fact that two planes are adjacent and border one another is no guarantee that they have similar life-support requirements.

This is where I've merged Færûn's Sword Coast (Neverwinter and Waterdeep, et. al.) with my own world.

Hyarfalas and the Southern Empire, including the Isle of the Dead
This great archipelago encompasses all of one hemisphere, from pole to pole. I haven't yet got around to prettifying this map, which is sadly faded from its glory days.
