Cryptoworlds

In Cryptorunners the world itself is like a giant chessboard, consisting of many smaller worlds called Cryptoworlds. They are square and surrounded by hot and thick fog that is pretty much impossible to go through, though it had once been possible to cross it, which at that time had not been too uncommon. The train Cryptobeasts from Choo Choo Town seem to be the only ones able to withstand the fog.

Cryptoworlds, while next to each other are also completely unrelated to its neighbours, and can have extremely different climate and terrain. Some cryptoworlds are not inhabited, while others are. Most inhabitants had never left their world, and many are even unaware of that there may be other places behind the fog. Cryptoworlds are pretty large, and it would take weeks to cross from one side to the other.
