The Law of Ether (Eeh-thurr)

In Adamius (Our dimension) We have a wide variety of radiowaves. However, in Leviathus (Earthion dimension), there is magic. These two properties are determined by two things: Uranium and Ethers. Uranium are scattered, loose conduits that can spread their energy or even transform it under the right circumstances, creating more powerful conduits.

However, Ethers, being almost completely permeable, are static and can only move as the ground shifts. These Ethers are the conduits of magic. These pink-purple Ethers containing magic energy leak it out into the world, and the plant and animal life inside these ethers works as usual, however with certain physical abberations or perhaps even runes on them. These runes are the cornerstones of magic. By drawing these runes and using Manna, over time, people have been able to conjure up many spells by combining, experimenting, and casting with these runes. Some are rarer than others, however, so some spell books have less than others. These runes also change places, so it is never a garantueed bet to go and copy something out of an ether.

Manifestation

Seeing a great, looming purple or pink cube on the horizon is the most obvious sign of an ether. If you are getting close to one, the plants and wildlife turn slightly purple-pink.

Localization

Magic is visibly stronger inside ethers, it is a common hero's rule not to attack a mage inside an ether, so many wizards make their home inside ethers. However, crops often die due to the lack of sunlight in an ether, so it is possible to wait them out. This effect happens to a lesser degree right outside of an ether, but not nearly as powerful as inside it.
