"Your highness" is gender neutral.
So you know, if you’re ever confused about my pronouns.
alternatively, “your majesty,” “my liege,” and “supreme overlord”
please note that “your grace” is also acceptable
some muggleborn like “i want to be an astronaut when i grow up!”
wizard kids like “wtf is an astronaut”
"oh you know…the people who go to the moon"
implying that magical children would know literally nothing outside of the wizarding world
