A funny thought about Malzahar...
With some recent Void lore releases, we got more information on Ancient Shurima views on the Void, principally those two quotes:
Thousands of years before Icathia unleashed the Void in battle, the primitive cultures of Shurima feared the devil Vel’Koz, who crept forth from the underworld to steal the dreams of wiser men.
It is the deep cold of the Void, which the ancients—in their ignorance—might have named as their underworld, and the source of all evil in the mortal realm.
So from this we can get that ancient Shurimans basically considered the Void the hell(well, maybe not the "bad people go there after death" part but you understood) and Voidborns were demons.
But then, we have Malzahar, a shuriman who worships the Void...but if Shurimans considered the Void the underworld and Malzahar worships it.
This means that Malzahar is the Shuriman equivalent of a Satanist.
Not something so important, just a funny thought I had while reading the lore.
