Also known as 
Hodur, in 
Norse mythology, 
Hod was the god of darkness and winter, the blind brother of 
Baldur. It was Hod who threw the mistletoe (guided by 
Loki) which was to slay the otherwise invulnerable Baldur.  For this crime, 
Odin and 
Rind gave birth to 
Vali specifically so he could kill Hod.
