Magic

Magic is the eleventh form of energy. Any other form of energy can feasibly be converted into magical energy, and magical energy can be measured in Joules just as any other form of energy. What makes magical energy distinct from any other form of energy is the ease in which it can be controlled. A being using magic can transform their normal bioelectric energy into magical energy through the brain. The brain can then channel the energy into a particular pattern, a Spell, so to speak. The more complex the pattern or spell is, the more intelligent a user would have to be to understand how to channel the energy into it.

It's ease of manipulation goes both ways, however. Any number of things can disrupt this process, but the most common disruptor is another form of energy. Powerful magnents and magnetic fields, as well as radioactivity can dampen affect the ease in which a user can channel their energy. Other countermeasures take advantage of Feng-shui, such as the Clasti Elder Signs and Dampening Symbols to create a negative energy flow or negative "Qi", which can break the users' precise hold on the energy.

Other users can even disrupt the spells from a distance, which is why most wizard duels take place with the opponents standing far away from each other, lest one disrupt the other's spells. Further, sapient wildlife is also capable of using its moderate brainpower to disrupt a magic user in while casting. However, such creatures are exceedingly rare.
