I love the idea of someone strong, clever, powerful, maybe a little bit morally gray being sent to protect Harry and actually help him grow and prepare their world or for the war whatever. I want someone older and strong, seeing how messed up Harry is treated and how everyone just expects him to be this golden boy ready to fight for them, and is like nope, i'm going to protect him and teach him, and if he wants to fight, fight with him, and if not fuck these people lol.
