A land far away.
For Beren son of Barahir had been sent by his father on a perilous errand to spy upon the ways of the Enemy, and he was far afield when the lair was taken. But as he slept benighted in the forest he dreamed that carrion-birds sat thick as leaves upon bare trees beside a mere, and blood dripped from their beaks. Then Beren was aware in his dream of a form that came to him across the water, and it was a wraith of Gorlim; and it spoke to him declaring his treachery and death, and bade him make haste to warn his father.
