Everything we've read is arcane and ancient tomes meant to document supernatural phenomenon with at least some accuracy, for the sake of future generations. They're like ancient textbooks. And also the team got information from magical experts on Sorceror's World.

Everything you've read is random morons posting whatever they think in their dumb brains on the internet.

That's the very definition of false equivalence, my friend.

Magic has rules and there's lots of resources on the study of them.
