First off, the setting of this world will be very similar to to the show MLP: Friendship is Magic, with a few key differences:

- I suspect we'll be using different place names which we can make up as we go, though it is entirely possible that we may want to use Canterlot/Ponyville/etc

- There will be a decidedly darker side to the fluffy flowery world of ponies.

- There will be troll ponies, space visitors to Equestria, we will figure this part out later emotion_awesome

- more when i think of it.
