One of the things about them I've wondered is are they really tempered or just slightly tempered? As yes we know they've summoned Ravana twice. One where the WoL fights them and the other when the WoDs do. Yet, we also know that some of them can just nope the heck out of the hive mind that is the One mind. Which goes against what we knew about Primals and tempering at the time and even the stuff we learned after that.
