The Price Of My Deeds in Gandalf

Isolated from this world,
As the deed is done,
No turning back,
Now my days are gone,
Hiding away,
From my future,
But I can't hide,
From my conscience,
I'm breathing but dead,
Imprisoned inside my head,
Darkness,
Never free again,
Light,
Never to see again,
All is lost,
No hope for me,
But for what I did,
This is the price to be.
