[b]Ok, here is the deal:[/b]
You know what, there can't be enough multiversal RPs or stories out there. And that's because the heart of the matter is it's concept and conclusion. A multiversa is infinite in its own fundamentality, even if it may be dwarfed by necessary existential forebears.

So, what'll this be about to stand from the masses you ask?
Well, let me put it this way. 
You'll have one hell of an egoistic GM overseeing it.
What, that's not something good?
Oh I think it can be.

Less sarcastically though, I have a few multiversal plots ready to be explored.
A classic travellers tale with the position as the hunted. (Not fleeing, simply a very long tactical retreat.)
One of those annoying crossroads places, it's not a freaking tavern though.
A world in need of saving, maybe from itself, maybe from your interference?
And some other more existential nihilistic philosophical debate regarding the multiverse itself.

Anyone interested?
(Or is there any questions needing answers first ^^)
