Among the dark woods not too far from the ghostly train station there is a small lake.

Upon the banks of the lake there are gnarled and knotted trees.

Amongst the roots of one of the trees and sitting upon a rock, fireflies dance about in a bottle…

… a bottle that perhaps holds a clue to the nature of what lies around you.
