When Beauty walks the Hallway of World she sees mirrors everywhere.
I'm a mirror, you're a mirror.
But we're shattered.
All the mirrors are nothing but empty frames.
And all the shattered pieces lay on the ground.
No one can ever say which part belongs into which mirror,
but we know one thing: you could not make a single mirror out of them.
The mirrors must be just about right size so Beauty could see herself in them in her wholeness, but more mirrors mean... more Beauty.

Our worlds are like planets. Everyone lives in their own little world. But all of them have gravitation. And we are the centers of the gravitational fields, centers of our worlds. And when two of our world collide, they both attract each other. But how rarely does this happen! There must be something special for the worlds to collide in the first place.
