Mystoerth is my campaign world for my *D&D games.
Back in the day I had learned to play D&D (Basic and Expert) with one group. When I got to high school, around sophomore year, I joined another group that was playing AD&D 1st ed. They were very entrenched in Oerth and Greyhawk. I was similarly entrenched in what was known as the "Known World" back then.
We decided our two worlds were connected by gateways and that worked out fine for a while.
We then attempted to make things simpler, and combine the worlds. We decided that they had always been like this, there was magic that had prevented people from traveling directly. Lame, but it worked. And then we drew a map. It was cool, but it had some issues. And then on my way to college I lost the map. We had not called it "Mystoerth" either then, only Oerth.
Fast forward many years and I find this map created by Chatdemon online.
It was perfect. So rarely does something you find on the internet fit so perfectly with an idea you have. This map is perfect. It really describes the world I wanted to play in. The best of Oerth/Greyhawk and the best of Mystara/The Known World. I added a bit of Blackmoor and I have the only world I ever needed.
Sure it is not 100% original. I write original material all the time. Sometimes it is nice to let someone else do the heavy lifting. Though I have done quite a lot of original work myself now.
This is the world I am currently using in my games with the my kids. The year is 1665 AC (Mystara) or 919 CY (Greyhawk), so plenty of time after the official material. This lets me break down some civilizations to run a "Points of Light" style game (4th ed) and have plenty of old ruins to explore.
Earth = 24,901 miles (Eratosthenes, 3rd C. BCE)
Mystara = 19,448 miles (Rules Cyclopedia)
Oerth = 26,110 miles (https://en.wikipedia.org/wiki/Oerth)
Mystoerth = 24,000 miles
This makes my world larger than Mystara. It also gives me (roughly) 2,000 miles "missing" from that map above (splinting the difference and looking at the map in Photoshop).
Here are my posts on the subject. I'll add more as time goes by.
