Trevelon_B - Profile

Inside, there were a couple of large cities, countless small towns and villages, forests, plains, and even lakes. Only one stairway linked each floor to another, and the stairways were in dungeons where large numbers of monsters roamed, so discovering and getting through was no easy matter. However, once someone broke through and arrived at a city in the higher floor, the «Teleport Gates» there and in every city in the lower floors would connect, making it possible for anyone to move freely through these levels.
