Types of Magic

Drawn largely from various head-canon and Vermillion.

Types
As explained by Zaqx.

"Well, for the rest of you, mages are people who obey the laws of their universe, but bend them in ways that might seem impossible to an outsider."

"For those of you who didn't have mages in your universe, they are fundamentally no different from an engineer."

"When you're done here [at Vermillion Academy], you'll have a set of powers that look like mage powers, but which function in any universe--even in ones that don't have any magic."

"There are many types of witchcraft, but the most popular type, and the type you'll be learning, is called Traditional Witchcraft."

"Traditional witches and sorcerers specialize in a single field of magic, but aren't limited to it. They can also travel between universes under their own power."

"The second-most popular kind of witchcraft is called Devilry."

"There are beings called Demons, who you'll learn about eventually, who saw traditional witchcraft, and tried to mimic it."

"Being naturally chaotic beings, they saw the normal behavior of witches and interpreted it as a strict hierarchy."

"In addition, they saw titles such as Witch of Memories or Witch of Mirrors and assumed they were the source of the witch's power."

"The immune system, which you'll again be learning about later, has a system which resembles witchcraft in several ways, called scrolls."

"Scrolls are a method of bundling up magic in a way that can be used anywhere. This resembles witchcraft, but is subtly different--A scroll brings a fragment of another universe's laws with it, so you don't violate them."

"I have another form of magic that resembles witchcraft, but is different. The rules I obey are always static, unaffected by the universe I'm in."

"Because my universe doesn't have magic, this manifests itself as an anti-magic field, which extends to things I'm touching--from fireballs to time loops, nothing affects me."
