- Save Gurthang! - He said. - Do not you recognize lord or loyalty unless the hand that holds you. Front of any blood back. So, you want to take Túrin Turambar? Want to kill me quickly?
And the blade rang a cold voice in response.
- Yes, gladly drink your blood, so I can forget the blood of Beleg my master, and the blood of Brandir murdered unjustly. I’ll kill you quickly.
Túrin signed then the hilt of the sword on the ground and fell on the tip of Gurthang; and the black blade took his life.
