Seven worlds

There are seven main worlds in this universe. They live alongside each other, but some are aware of the existence of others.
==The Real World==
This speaks for itself. The world we live in now.
==The Farlands==
Includes the Nether and The End.
==The Shadow World==
A shadowy place, from which came the Dark Master.
==Marco's Dream==
A world created by Marco and Amely.
==StarGate Village==
This is where all the members of StarGate Inc. reside.
==Ender's Mind==
Yes, this is a world. Everything here is part of Ender's memories, thoughts and feelings.
==The Citadel==
Only a select few are allowed to enter this realm. Time does not exist in this zone.
==Sub-worlds==
These are special. They include:
* The Matrix
* Exor
* The Aether
And many more besides.
