Capítulo 420: Traitorous Bastard.

Helios was born and bred in the plane but it is obvious that there are a lot of strange unknown things about the son of the sun god. So as absurd as it might seem, Helios could be related in one or another to the demon invasion.

It could also be the sun god that is responsible for this invasion. That traitorous ancient bastard certainly has had a lot of time on his hands to dabble in a lot of things. He might have some contact with demons because he was alive back in the day when demons used to attack the plane. This might be his plan to distract the divine plane from his betrayal or to weaken the divine plane. 

Then there is the hidden god that wants to ruin his order. That god might be the architect behind this attack too. It became more plausible the more he thought of it. The hidden god might have gotten in touch with demons to create chaos in the divine plane too in order to further its nefarious agenda.
