UNKNOWN.

If you search for me
One day to find me gone
You found me long ago
For I am where
I've always been
Standing beside you
Clearing a path
For your journey
Of which I've passed through
For I am a shadow
In the darkness of light
And here is where I'm captured
Beyond the unknown
Of which there is no fear
For the Sun's warmth
That I no longer feel
I guess it is 
That I am
When I see its light 
Reflected upon you.
