There is not much to say about Hödr. He was the twin brother of Baldr, one of the sons of Odin and Frigg. The Norse prose mentions that even the gods do not want his name to be spoken, as it would remind them of his deeds.
Hödr was blind. Our sources do not mentioned whether he was born that way to our world. It could be the case that he had lost his eyesight in battle as his name means “warrior” (although that is pure speculation).
As far as we can tell, Hödr was good-natured. Loki tricked him into manslaughter, after which he was sentenced to death by the other gods. He would later be killed by his one-day old half-brother: Váli.
