On the map, the school campuses appeared as thousands of identical numbered rectangles dotting the planet’s surface. They were separated by rolling green fields, rivers, mountain ranges, and forests. The forests were of all shapes and sizes, and many of them bordered one of the schools. Next to the map, I pulled up the Tomb of Horrors module. Near the front, it contained a crude illustration of the hill concealing the tomb. I took a screenshot of this illustration and placed it in the corner of my display.
