§ Of Túrin Turambar The Silmarillion

Then Mablung was dismayed, but needs must tell to Túrin how Morwen was lost, and Nienor cast into a spell of dumb forgetfulness, and how she escaped them upon the borders of Doriath and fled northwards. Then at last Túrin knew that doom had overtaken him, and that he had slain Brandir unjustly; so that the words of Glaurung were fulfilled in him. And he laughed as one fey, crying: 'This is a bitter jest indeed!' But he bade Mablung go, and return to Doriath, with curses upon it. 'And a curse too upon your errand!' he cried. 'This only was wanting. Now comes the night.'
