world B. Bad places.

There are bad places.
Something may have happened there once, and stained that place.
Or that place may have always been that way.
Trees grow tortured there. Twisting around themselves, as if in pain.
You can't be there too long without feeling it too.
Without it affecting you.
That darkness.
Such places can't make you do something against your nature, but they may have a use.
A place to go to find your true depth.
How deep that inner blackness goes.
A place to go if you have a need to do something truly, truly terrible...
