" Grendel was that grim creature called, the ill-famed haunter of the marches of the land, who kept the moors, the fastness of the fens, and, unhappy one, inhabited long while the troll-kind's home; for the Maker had proscribed him with the race of Cain. That bloodshed, for that Cain slew Abel, the Eternal Lord avenged: no joy had he of that violent deed, but God drove him for that crime far from mankind. Of him all evil broods were born, ogres and goblins and haunting shapes of hell, and the giants too, that long time warred with God--for that he gave them their reward. "
