The Creationists study the effects of Positive Energy.  In addition to the four Elemental Energy Planes, two other Energy Planes exist; the Positive Energy Plane, and the Negative Energy Plane.  Much like the Elemental Planes, these Planes exist as pure energy.  Where they touch the Material Plane, however, they have a much different effect.  When Positive Energy touches the Material Plane, it acts as a constructive agent, growing or strengthening whatever it touches.  It's effect can be seen in healing and growth in living creatures, and in things such as crystals and light in inanimate things.  Creationists seek to study and learn the secrets of Positive Energy, and how it can be harnessed and controlled.
