Comparison of Metaphysical Forces in RJO

RJO has several different metaphysical forces at play, and it is useful to know their differences. Some powers are usable by anyone, only requiring study; others are limited to certain people. Some differ in application of philosophy or hard sciences, and most have different primary applications.

The Force
The Force is an invisible energy field that flows through everything and binds all life together. Most people can hear it, but only select people can learn to actively use it. The Force is also sensitive to people around it, so it must be used from a clear, calm state of mind. This is called the Light Side. Used from a place of anger and hate, The Force will poison its user and the surroundings. This is called the Dark Side. RJO's philosophy on the Force is heavily based on the Jedi Order's, but is different enough that they refuse to call themselves Jedi.

The Force transcends even time and place, giving Force-sensitive people the possibility to see into the future.

Alchemy
Alchemy draws its fuel from the movement of magma in Earth's mantle. It is the thorough study and understanding of matter that allows alchemists to break down and reconstruct matter into a new form. Philosophically alchemy has similarities to how the Light Side of the Force is achieved, but alchemy deals strictly with the physical world.
