The Castle Marks the kingdom below

The Castle Was Built by hand upon one of three large, neighboring mountaintops. The towers reach to the height limit of the map, and using a world editor I have Excavated the interior of the mountain to the bedrock, and began construction on one of the half dozen kingdoms I plan to build below the surface. I also began construction on a small bridge which I intended to have be one of multiple constructed to link the mountain range to those adjacent.
