Well I'm going with a Xross wars setting style in world creation.

Meaning several different 'Area's' excist within the world usually specifically created for one purpose or type. New areas can be accessed through gates which link the digital world since nobody 'directly' own them. 


The Tone will be a Cram topped choco-latte that's shaken and not stirred. 

There will be cream.
There will be chocolate.
There will be milk.
There will be sugar.
And then ther will be the Darkness that still remains in the Coffee. 

So yeah.

The theme will be inspired by the first series. All humans are put on a buss supposedly going to a youth camp, however the buss takes a little 
'Digital' detour, meaning nobody in theory will miss you while your gone for quite a while.   

Hopefully that do sound more reassuring than my 'The Dm is out to kill everyone' settign *Grins*... oh did I say that loud?
