I'll eventually put up info on various of my attempts to portray Mystara in a Birthright System. My starting point was Solmyr works, and to a lesser extent that of Rob's SC varient, but I've been refining it in various versions for quite some time (currently working dually on Versions 4 & 6). Marco Fossatti is also doing an Alphatian version.

My 1st version was basically as Solmyr's conversion, with some stuff added based on Rob's modifications to the Savage Coast

My 2nd version I only changed slightly from Solmyr's. I added to, but never reduced, replaced, nor removed anything of Solmyr's. Added Some minor flavor text. Expanded to a few new area's (ie the Alatians)

My 3rd version was were I finally started to make significant changes and departures from Solmyr's base. I briefly had a PBEM of this version. This was the first time I got confortable enough to tweak Solmyr's holdings.

My 4th version, is the most complete form I've compiled and is one I'm still actively working on. I systematically went through every entry I had. I've got most of the Known World (Thyatis is not yet complete) and some places elsewhere (erratically) completed.

My 5th version was basically a disaster I'd like to forget about. I tried to add in too many new rules and too many micro-details. This was also my first attempt to break away from Solmyr's maps.

My 6th version is an attempt at adding the RoE style holdings (Manor's & Trade) along with some rules mods like the Silveras style mods (which I had also tried in v5). This is the other version I am still working on, but I've just started.

I'll add more notes when I have more time.

For now, I have notes up on Alfheim & The Broken Lands
