Lex's thoughts wandered back to the map of the Crystal realm. He'd seen it for less than a minute, but even so, it had revealed a lot of information to Lex. Of the many things he learned, the most unbelievable was that the Crystal realm was flat!
It consisted of hundreds, possibly thousands of continents, and how deep the ground went was not revealed on the map, but the borders where the realm ended were clearly marked. About 1000 miles (1609 km) from the edge, on all sides, was an absolute dead zone, where no living thing could enter. The edge of the realm did not open into nothingness, leaving the realm as if floating in space, but was tightly blocked. On this, there was too little information, but a preliminary guess Lex made on his own was that there was a solid wall of space blocking off the edge. Of course, Lex's understanding of space was entirely based on fiction novels, so there was likely a better explanation for it.
