Light/dark energy

Light and dark energy are the two charges that any molecule can have. The ratio of light to dark particles in a molecule determines quite a bit about a molecule, including it’s element, it’s mass, and even if it is sentient or not.

Light energy and dark energy have the same energy counts as each other, and a darkly charged particle will have the same energy as a lightly charged particle. The only difference is how easily a molecule can be harnessed. Darkly charged particles are much easier to be harnessed than lightly charged ones.

Dark energy, unlike what you might assume, is not inherently evil. By the same logic, light energy is not inherently good. It’s just a coincidence that most heroes choose to use lightly charged particles while most villains choose darkly charged particles.

In fact, the amount of dark or light energy in the Multiverse doesn’t actually directly matter. The only reason why dark energy is tried to be kept from spreading is because The Magician has mastered harnessing dark energy, and it would give him more power if it became overrun with darkly charged particles.
