Okay, so everyone knows that Young Wizards and Harry Potter are different things, right? Really different. One of the best comparisons I’ve heard is that magic is a right in the HP world, and a privilege in the YW world.
Yet it’s also close to canon that the YW ‘verse can encompass all fictional universes to some degree. So how do we reconcile this? I will talk about this under the read more.
Ooh, this is interesting! And what if the HP universe is a variant in which the human Choice went very differently, thereby affecting humans’ relationship to magic on a foundational level from the start?
Also, let’s point out that Harry’s uses of nonverbal wizardry as a young boy was to ease his own pain (and that of a boa constrictor)? He inadvertently adhered to the Wizard’s Oath even though magic in his universe does not function that way.
Magic’s passed down genetically in the HP universe, so the wizards in HP do not have to adhere to the Oath. That’s why HP has dark wizards and YW does not: because in YW, like OP said, magic is a privilege, and no heart willing to use magic to speed up entropy would retain that power.
I would say that Earth’s Choice in the HP universe was to bind all magic on the planet into a few select species, but allow each to formulate a personal Choice regarding the use of their magic. This explains why there are magical creatures and nonmagical creatures, and why the morality of wizards is up to each one.
Oh wow, I didn’t actually realize that about Harry+noverbal magic when I wrote this! That’s really excellent!
