Wait which awa are you?
Anyhow I am pretty sure I talked about this with Steph on twitter before and I love the idea, honestly. I think Oz would know about Mitile's prophecy and still just... Still raise him to be strong. But I do wonder how this situation happened cause that would really change everything. Like... Did Tiletta go back to the north to give birth to Mitile? Did Maurice die? Or is Oz a southern wizard? It's hard to envision her entrusting her kids to the world's least qualified Guardian so the details would matter a lot in this case.
But I can very specifically see Figaro raising Arthur being very intentional about "you have to make the world better for wizards when you inherit the throne one day". I love them so much
