Yeah could be that Order is just cause of Tyrhold.
We did get Spirit btw. In Pandaria. I am guessing all the Azerite is pretty spirit infused given that's what Azeroth eats.
So, speculation time. Anyone has any idea what the Titans might have placed in the Dragon Isles before bring the Dragons there? I mean sure it could just be Tyr giving them a home but they are probably guarding something. Or it really could be nothing.
