I'm here to finally talk about the world I made for a story for one of my OCs (my dearest darling emo Veronica) and that I've been currently making a sanders sides au in. I don't have a name for it yet, but oh well.
First of, the setting: it's a pretty normal modern setting, but with magic.
Next, magic! The three main things that determine someone's magic ability:
Raw magic, everything has a set amount of max raw magic, the more raw magic you have the more spells/more powerful spells you can perform before you need to rest (basically mana/spell slots)
knowledge, knowing how to utilise your magic, things like spells and rituals, the theoretical stuff.
And lastly proficiency and control, knowing how to use your magic in practice, the more used you are too using your magic the more control you have, the less raw magic goes to waste..
There's witches, humans, magical creatures, and the children of witches/humans and magical creatures(i don't have a term for it yet)
Everything has an amount of raw magic, but witches have a significantly high amount of it, and the inherent unique ability to tap into it.
Humans still have magic, but a fairly low amount, and can't really naturally tap into it. The only noticeable physical difference between humans and witches are the ears, humans have round, witches have pointy.
Magical creatures are full of magic, but they can't utilize it the same way witches can. There are three main categories of magical creatures.
Fauna: magical animals that live in the world.
Spirits/elementals: they embody parts of the world/ concepts.
Demons: beings from different worlds/realms.
Magical creatures often serve as familiars for witches due to their ability to absorb raw magic, and transfer it. They form a symbiotic relationship with a witch, where they absorb excess raw magic from the witch, which helps keep a witch's magic levels stable and manageable, and when needed they can boost a witch during spells by channeling the magic they've gathered back.
The offspring of a witch and magical creature used to be feared, due to people thinking they would have the ability to cast powerful spells by absorbing others raw magic. But no, they can absorb small amounts of excess raw magic, but not much, and they don't really have the inherent ability to use it the same way witches can, they really just got the short ends of both sticks
That's all for now, hope it made sense
