Side note on the update. I've noted that Mathilde referred to the Chaos Dwarves as "Fire Dwarves". Not super indicative since that's the literal translation of Dawi Zharr, but I suppose it's notable since it's a lesser used title for them.
The inherent assumption that Hashut is a Chaos God is the sort of debate starter you learn not to throw around in academia unless you've got a bunch of time to kill.
