First World - Kaos

Finished the expac.

First things first, it was a great experience. Loved it.

After beating the expac boss, a second portal to Kaos opens up. When conversing with Stribog (God of Wind), he mentioned that the world is full of fungal & insectoid creatures but if we're really unlucky, we can encounter a demi-god in there.

So, my question is, what Demi-God is he referring to? I have already discovered and beaten all the demi-gods, save for the desert dragon, Baba Yaga and the Iron Guardian.

Also unrelated, during Djabog's quest, is there no way to fight the Beast? I see to only be able to trap it.
