Jörmungandr was the son of Loki and the giantess Angrboda. He was once a resident of Asgard, home of the Æsir, the Norse pantheon. However, he was banished by the king of the gods, Odin, to the great sea that surrounds the mortal world of Midgard. Odin had hoped that Jörmungandr would be destroyed by the ocean’s relentless waves, but instead the serpent began to consume it. The next time he was sighted, he had grown so large he could encircle the entire planet and bite his own tail.
