Death of Glaurung

Shrewd and malefic, you father of the dragons
 By your enchantment, Nienor was bewitched
 On the treasure of Nargothrond you wait
 For your vengeance, in the twilight of the day
 The time has come, you're ready to destroy
 By fire and flames the sky turns to red
 At nightfall near the shore you stayed for some rest
 But Túrin drew his sword, he gave you a painful death!
 "Hail, Worm of Morgoth! Well met again!
 Die now and the darkness have thee!
 Thus is Túrin son of Húrin avenged"
 He then wrenched out the sword
 But his flesh was set a flame
 By the black blood hoard
 The venom burned so that he yelled in pain
 Dying in the night it told the truth
 Of the doom he left behind
 He realized what he had done
 His pain led him to death
