Hod
The son of Odin and Frigg, he is a blind God who died before Ragnarok during the poisoning of Baldr; tricked by Loki, he fired a poisoned mistletoe dart at Baldr and killed him. The The God Vali in turn slew him, a beserker God born of his own father Odin and a giantess named Rindr; he matured within a day for the sole purpose of killing his blind brother in revenge for what Odin percieved as the murder of his eldest.
Hod was unable to return during Ragnarok to fight due to his blindness, but even though dead, is still called upon for aid when the path is unclear.
