The theory of the Kamidogus is more of the same old story getting retold of getting super powers from daggers. Also being corrupted by it unleashing a lot of evil in the process and in doing so may unleash the big bad himself. The mystery of it all is cool though.

So Raiden brings Chaos to Earthrealm and red clouds form, so maybe Havik is involved, but I just cannot see how. He needs to appear in the comic at least.
