Actually, now that I think about it, what are opinions on god-god relations? I've said that they'd produce higher-tier demigods, but do you think such a union should produce a god? Opinions?

Logically, it'd make sense. Hmm... 

Well, Hephaestus and Ares was born from Zeus and Hera, if my mythology is correct. Poseidon and Demeter also got Arion the horse for a child. 

The only time I've seen God + God = Demigod is the stupid Disney movie Hercules, because fuck Disney.
