This is about the mechanics of magic in a world where all power stems from one being. This being does not necessarily want others to know that this is the case, and so it creates a consistent system of magic for others, wizards and magicians, to use. Where this being gained the power of magic is irrelevant, all that matters is the system which it has built up.
Magic is the ability to modify the world in any way, without limitation. The wielder is omnipotent, able to alter the world at a thought.
True magic, as opposed to indirect magic (next major section), does not have any rituals, incantations, or spells. Think of it as like moving a limb: you don’t direct the operation of your muscles, it’s a wholly subconscious process. True magic is the same: the wielder does not direct the magic, they just want the world to be as it is not, and the change happens.
Wielders of Magic
There is only one wielder of true magic at any given time. This being is, for lack of a better term, God.
The Transfer of Magic
A wielder of magic can transfer the power to another being. This is a total transfer of power: it’s not possible to conditionally grant power, or to grant some power but not all power. It’s an all-or-nothing deal.
If the current wielder of magic dies, then the magic dies with them and the world becomes a sadder place.
Indirect magic is magic performed by the wielder of true magic (hereafter “God”), on the behalf of someone else (hereafter a “magician”). From the perspective of the magician, they are performing the magic. They draw the circles, wave their arms, say the spells, and the world changes. They don’t know that what actually happens is that God notices this and performs the appropriate effect at the appropriate time.
This is a lot of work for God, but as He is an omnipotent being it’s not that bad.
Magicians believe they have magical power. They do not know about true magic, or that what they do is indirect magic. They are deceived, and would be horrified to learn the truth.
The Age of Myths
A time in human history when the population was small enough for God to monitor the entire world, and perform indirect magic as He saw fit. Mighty sorcerers walked the earth, calling forth power from their fingertips with a shout. Monsters lived in the dark places, and heroes wielding magical weapons hunted them down.
It was an age of chaos, where just about anyone who God liked the look of could cast arbitrary magic. But as the population grew, it became more work for God to keep everything going. This led to God creating a more ritualistic system of magic, which was gradually revealed to the magicians of the Age, and the non-ritualistic system phased out over centuries.
The Magic Machine
The Magic Machine is a device created to monitor the world, and let God know when magic should be performed.
It is a fairly intelligent machine, but a machine nonetheless. It is only capable of recognising what it has been programmed to recognise. This explains why ritualised magic incantations and drawings exist: they are composed out of a magical language which the machine has been created to recognise. When a magician casts a spell, they are communicating a program in the magical language (even though they may not know the full details of the magical language), which the Magic Machine recognises and communicates to God. God then performs the appropriate effect.
The creation of the magical language and the machine has greatly lessened the burden on God, at the cost of a much more rigid system of magic, and the end of the Age of Myths.
