Scariest Thing In All Of Tolkien's Creation...Ever

[Lalaith]

The fate of Hurin scares me more than anything else in Tolkien:

hen Morgoth cursed Húrin and Morwen and their offspring, and set a doom upon them of darkness and sorrow; and taking Húrin from prison he set him in a chair of stone upon a high place of Thangorodrim. There he was bound by the power of Morgoth, and Morgoth standing beside him cursed him again; and he said: 'Sit now there; and look out upon the lands where evil and despair shall come upon those whom thou lovest. Thous hast dared to mock me, and to question the power of Melkor, Master of the fates of Arda. Therefore with my eyes thou shalt see, and with my ears thou shalt hear; and never shalt thou move from this place until all is fulfilled unto its bitter end.
And even so it came to pass; but it is not said that Húrin asked ever of Morgoth either mercy or death, for himself or for any of his kin
