The Modeus Grid is a system that defines battle sectors, known as Regions, across the realm. This grid was conceived by Asmodeus to chart the theater of conflict during the Demon Spawn War, which spanned the years 89 GE to 269 GE. The maps of the realm continue to utilize this strategic mapping approach.
