Bor

Bor was the second King of Asgard, Odin's father, and Buri's son. He fought the dark Elves and defeated Malekith. Knowing the Reality Stone could not be destroyed, he had it hidden away in the chasms of Svartalheim. However, Bor would not be aware that the Aether would accidentally be discovered by Jane Foster nor that it would inhabit his great-granddaughter, Torunn. He was succeeded by his son.
