So... I have a theory

We all know that Venomshank went beserc in the 'CROSSROADS MUST FAL' trailer, and he'd gone beserc because Sword is missing. And we all know what Firebrand burned down the The Lost Temple for an unknown reason. Well I think that Firebrand also destroyed Lost Temple in the search for his child.

But that's not all

I think that Darkheart is connected to that?! 'But how?!' Well Darkheart is a deity of chaos. And what else will cause chaos, his siblings going mad. And how would he do that, simply take their children. Darkheart might have manipulated Firebrand's kid into becoming a cult leader or something similar to that

Plus, I think that Illumina works with Ghostwalker in order to try to stop Darkheart from causing more chaos in Inpherno (and partially because I headcanon that Illumina lost his wing in a fight with Darkheart)

This theory is based off of @kota_kore on YouTube, go subscribe to him
