No More Learning

'But when we left, in those deep woods we found
A knight of thine spear-stricken from behind,
Dead, whom we buried; more than one of us
Cried out on Garlon, but a woodman there
          of some demon in the woods
Was once a man, who driven by evil tongues
From all his fellows, lived alone, and came
To learn black magic, and to hate his kind
With such a hate, that when he died, his soul
Became a Fiend, which, as the man in life
Was wounded by blind tongues he saw not whence,
Strikes from behind.
