Theory about Ornn and Volibear fight.

I read much information about those two guys,a demigod of fire and forge Ornn,and a demigod of thunder Volibear.

In true,when Ornn was revealed,i was curious about why Volibear wanted to fight with him own brother,but after reading the new short story,Silence of the damned,i get it,it's only a theory but it have sense.

By my opinion,Volibear was corrupted by something ancient and evil.Why i think he was corrupted?well,let's see one Ornn quote:

This quote will say Ornn when he moves near Volibear:

"Singed fur... Jealous blood... My brother is near!"

At the first sight i didn't attach great importance to it,until i read the short story,there we can find a thing,what shows to us what with Volibear something happens,because not just like that Ornn say "Jealous blood",as i think the word "Jealous blood" it's metaphor.

Here one moment from the short story:

"** From its mouth, an unnatural, black blood dripped.**",black blood..there is something wrong,it is?

Here is my theory about this:

When Ornn was forging and teach the humans to blacksmithing,Volibear find on the outskirts of Freljord something mysterious,from curiosity Volibear come near to it,and that thing corrupt him mind and make him to fight against him own brother Ornn.

As i hear,Volibear is on the rework list of Riot's,and i hope my theory will be as half right, because it fits well as i think.
