The dreamscape

The place where everything is possible, and everyone can create whatever they want, but only when sleeping.

Geography

You can find absolutely anything within the dreamscape. Mountains, forests, oceans, floating islands, cities made of gold, whatever you can imagine. The only restriction is in terms of area. Each dreamer can only create so far they can see, and if they try to move it's their part of the dreamscape that shifts. This way no two dreamers ever meet each other, always staying in the same place.

Fauna & Flora

There are as many variations in creatures and plants as the geography, but they aren't actually alive. Instead, they can be seen as part of the landscape, just moving in relation to everything else.
