The sight Below (riddle)

The Pale voyager in the dark looks down

Upon the sight giver far, far below.

The sight giver is hit.

It quivers and runs in every direction.

The Pale voyager gazes down from the sky with curiosity.

The uninvited moves past the place

Of the pane of sight with caution.

The giver of sound wails for his friend whose pieces ran so free.

Fear fills the uninvited, making him flee.

Mr. Light comes rolling by flashing blue,

To mourn the death of the giver of sight.

The pale voyager looks upon the sight below

The next night she hides her face,

With disgust for what she saw unfold.

Now all that is seen is half a sight,

A face now turned away with sorrow,

Instead of the usual pride.
