You know, I feel like even having eight different types of magic may be going too far, because then there is a bunch of extra information for people to remember about what goes under what element, and as stated before, one of my goals is to minimize how much corrective action I'll have to take to keep people within boundaries. So, here's what I'm going to have in the main thread when it goes up:

The Mortal Planes are parallel universes that co-exist in the same space at different vibrational frequences and are connected through various Prime Nexus Points where travel between them in possible using various magical means. Earth is one such Point. 

The Aether is a realm of raw energy and power that surrounds the Mortal Planes and penetrates them, like the Force in Star Wars. All magic is fueled using Mana channeled from the Aether. 

There are three types of magic:

Natural Magic: Anything that converts Mana into some physical energy or structure in the world, such as manipulating or conjuring the elements, casting healing spells, bending light, crafting illusions, affecting gravity, teleportation, time-travel, etc. 

Psionic Magic: Does not create or conjure anything, but rather uses Mana to fuel psionic abilities such as telekinesis, telepathy, and the various other kinetics. Basically, you can control what is already present - including the elements - but you cannot create anything new. 

Chaos Magic: Only theoretical, said to be the limitless magic of the Celestials, who are thought to have died out millions of years ago. 

The Arcane Tongue is a metaphysical language that was embedded into the fabric of the Aether by the Celestials. Vocally, there is only one dialect the Aether recognizes, but there are over a dozen different runic translations that can be used. Just use your imagination for that, I will not define specific words or phrases. 

Basic magic can be done at will, but more complex applications require use of runes from the Arcane Tongue, which are engraved onto your Arcane Conduits, such as wands, swords, amulets, etc. You can also utilize a grimoire with spells written in the Arcane Tongue and channel Mana into the ink to activate the spell. 

Anytime the Arcane Tongue is spoken, use triple brackets. {{{"Like this"}}} You may use this method to call out spells and have that vocal component in the Arcane Tongue act as a Conduit as well. 

I may add a few extra details with the main thread goes live, but I want to keep information needed for co-writers to remember to an absolute minimum.
