Here everything is. If there are any problems let me know. The mod and maps are compressed into 2 files(1 is a zip 1 is a rar) straight from my 'C:\Program Files\Infogrames Interactive\Civilization III\Conquests\Scenarios' folder. Just drop the 'tjedge's D&D-Mystara' folder into your '...conquest\scenarios' folder, where ever you have it on your computer. Same for the maps(I recommend using the included 160x160 world map with assigned start locations).
Maps size: less than 1 meg
Full Mod size: 571 megs
Enjoy.
Peace out, V-Crack
P.S. Sorrry about the file service pop-ups, they were cheap, I mean free.
