Magic is a technology, but it is still magic within the rules of this reality, it is both. The magic, as with everything in nature, is a sort of feedback system. The emotions and consciousness of the witch travel from this reality through a binary interface. This interface cleans out everything from this reality that could infect other realities and makes it safe for the divine to interact with. The reply then returns to the consciousness of that same witch. The witch senses the response and it serves as inspiration for her spell creation. As the witch creates the spell, the divine being sends changes through the interface to bring a convergence of coincidences in line with the spell - this is what we call magic and the divine calls "cosmic consent." This assumes that the witch is an angel witch. However, as not all people are good, not all witches are either.
If the witch is evil, then the interaction happens the same way but the spell casting and cosmic alignments are influenced by the evil-force in the cosmos. Thus the cosmic alignment of the witch is vital. They are either angel witches or satanic. Witch hunters never really got that part, so they killed the only ones capable of saving them... and then prayed for angels to help them... the irony wasn't lost on the magical community... or at least those who survived the genocide.
If you can't make your own spells you can't do magic. It's that simple. The words work because they are part of living language and culture, it is the special way those sounds interact with neurology that give the divine universe a chance to win and make necessary changes. So witches are clever... scary clever... and that is why their discovery is always their own halloween. People are frightened of brains more than twice as clever as what they consider genius. So, if you can't lower your brilliance, they best you can do is only let it out a bite at a time and spread it thin. So, if you can make and cast spells, this is your caution and this is why the universe hides you. One never reveals the ace until the time is right. Every good witch is an ace in the hand of the divine cosmos.
I can help you with spells, but that's it. I'm not part of the magical community. I'm a lone wolf, a freelancer if you will. I am an angel witch though, or angel warrior, which are similar but not the same. I just happened to become both. It's my personality I guess.
The Fay have begun to undo the chasm, the spell casting. It takes time and there can be turbulence before a safe touchdown. You have an element of spell "cast sting" all over the world as different "casts" "tribes" or "peoples" sought to gain advantage over others. It is there right from the nanoword, to the words, to word combinations, to puns and metaphors. It's gonna take a while. But we are familiar, we are au fait, we are ofay, with the issue. We have their number. We are on it. We got this. Trust your local faery dealership and they will provide a car with zero sting. Welcome to a world with real magic and real magicians.
