This and this are inspiring a new setting. It involves dimensions collapsing into each other to form a new place for things and people to be in.
Especially player characters!
Also, Vornheim will be there too.
I've been making notes on the three "realms" that will make up the setting, and formulating the basic adventure thread. The gist is this, "For better or worse, but most likely worse, you are now here. To get elsewhere go to this other place, it is very far away and the road is dangerous."
I'm stealing Stephen King's cosmology, too.
I told the whole premise to a guy who had sworn not to play D&D again and he said, "Yeah... yeah.. I could dig that."
So I think it might turn out well and good.
