/Region Explination\

So... This is a Nightmare and Dream region. That's explanatory.

So, basically how this works is a mist that can appear ANYWHERE (D&D fans, if y'know, y'knkow.) It swallows you whole if that makes sense. And when you re-emerge, you're not in the region you were before, you are in a region known as the Frightmare.

In this region, you have to survive all the Pokémon because they are out to kill you.

If you're lucky to escape, you will end up in a Dream Region, where all the Pokémon want to help and he your friend.

But when you return to wherever you came from (if you do) you will never be the same, and every time you go to sleep, you will either have a dream about the Dream Region, or a nightmare about the Frightmare region.
