The Knights Moralis are the villains
From what I’ve seen in the show the way witches choose apprentices happens in one of two ways, either a witch for whatever reason decides to bring an outsider into the fold or the far more likely way they are the child of a witch.
As seen in the show, this has already created a pseudo nobility not tied to any singular nation, but the international magic government policed by the Knights Moralis so they can do as they please and enforce their laws around the world. But this international Noble class cannot truly be overthrown as they and they alone have the power to effectively cut off all advanced industry in the world at the slightest provocation.
The Knights Moralis are what the the KGB and Gestapo wish they were they’re the most oppressive and effective secret police force imaginable, and the only resistance to this regime is 10 people who somehow have a fraction of the secrets that this government keeps in a library locked away and never to see the the light of day again.
Even though the Brim Caps certainly do evil things. Their goal might actually be in people‘s best interest, and I have a feeling that the stories of how this magic government came into existent aren’t quite as black and white as the show currently portrays it. But I’d love to hear people’s takes on the store so far.
