I think it's clear from the write-up that classical_hero was Odin. The jotun taunted him by saying, "So, you have problems keeping your eyes in this world too?" which is a dead giveaway. I'm not extremely familiar with Norse mythology, but I know that Odin gave up one of his eyes in exchange for knowledge.

So there was only one murder last night? Interesting. And I'm not clear why Kagemusha died from the holmgang. I assumed the accidental blow to the bystander was just the intro to the duel, but did the bystander actually take the place of one the participants? That's quite odd.
