When these giants became aware of the existence of the god Buri, and of his son Börr (born), whom he had immediately produced, they began waging war against them, for as the gods and giants represented the opposite forces of good and evil, there was no hope of their living together in peace. The struggle continued evidently for ages, neither party gaining a decided advantage, until Börr married the giantess Bestla, daughter of Bolthorn (the thorn of evil), who bore him three powerful sons, Odin (spirit), Vili (will), and Ve (holy). These three sons immediately joined their father in his struggle against the hostile frost-giants, and finally succeeded in slaying their deadliest foe, the great Ymir. As he sank down lifeless the blood gushed from his wounds in such floods that it produced a great deluge, in which all his race perished, with the exception of Bergelmir, who escaped in a boat and went with his wife to the confines of the world.
Here he took up his abode, calling the place Jötunheim (the home of the giants), and here he begat a new race of frost-giants, who inherited his dislikes, continued the feud, and were always ready to sally forth from their desolate country and raid the territory of the gods.
The gods, in Northern mythology called Æsir (pillars and supporters of the world), having thus triumphed over their foes, and being no longer engaged in perpetual warfare, now began to look about them, with intent to improve the desolate aspect of things and fashion a habitable world. After due consideration Börr’s sons rolled Ymir’s great corpse into the yawning abyss, and began to create the world out of its various component parts.
