These two maps are the starting point for my own version of Mystara, which I’m calling The World Unknown. The setting has been devastated by an invasion from alien-like Immortals from beyond Mystaraspace. These alien Immortals invaded using massive asteroids/meteors that they directed at Mystara. After impact, the primordial Immortal beings crawled from the craters, along with armies of minions, and laid waste to much of the world.
This first map is, of course, the tradition region of the world of Mystara, the Known World. A great deal of this region has been destroyed by The Undying Devastation. (The invading Immortals refer to themselves as the Undying.)
This second map shows northern Davania as in appears s part of The World Unknown. This map is less complete than the one above and is likely going to be modified a lot more. In this new Mystara, Davania’s power has grown with the destruction of so much in the northern lands.
There is another Campaign Cartographer map that details a campaign expansion. However, I’m going to modify it into a Hexographer map before posting it here.
The setting has an old thread on The Piazza, which I’m going to revive. It has been a while since I looked at The World Unknown, so I need to go through everything and refresh my memory.
The setting is meant to be a prime material world in my Mirrored Cosmology, which was originally designed to be the cosmology for World of Kulan. You can see the details about that cosmology on The Piazza: Knightfall’s Mirrored Cosmology
