Actually, it's a little-known fact that the entire Homeland series' sole attempt was to support my Asylum theory that the Leveller cannot be killed until he is decapitated. If you're like most people, Thorago got his head smacked off by a Shalam - trapping them in the ice just won't cut it!
Seriously though, you can think of it as a prophesy, because it takes place after Myth II, and although it introduces some names from the past... that's really nothing to debate.
I'm glad to head that some of you think of Homeland as being on-par with Chimera, story-wise. Believe it if you want, but there's not much to debate.
