The Light and The Darkness

The Light and The Darkness are two Elemental Powers that have existed since the time of the Arkeans. It is stated that as long as these two Elements remain balanced, conflict will always continue. At the end of time, there can only be one victor; the Light or the Darkness.

The Light
The Light is an Element that, as the name implies, bring light into the universe, thus blessing it with life. However, it is heavily implied that the Light is not the Element itself, but the concepts that people have: If the Light wins, the Darkness will forever be purged, and the universe will be eternally peaceful.
 *  Good-  Anyone is capable of developing a heart devoid of evil.
 *  Life-  All things living and breathing, nature, souls hanging in limbo, and so on.
 *  Creation-  Imagination is boundless and wondrous.
 *  Positive Emotions-  Happiness, strong bonds, and so on. Even sadness could apply to this because it helps people to grow.
 *  Love-  Perhaps the most powerful emotion there is. It can be unpredictable and can be as powerful as any Arkean. Even the mentioned species is not immune to falling in love.
 *  Hope-  This fills people with anticipation for the future and results in great planning.
 *  Peace-  Not just peace on Earth, but among all the races of the universe; humans, animals, gods, and so on.

The Darkness
The Darkness is an Element that is able to swallow light and eclipse the universe with darkness. However, much like its counterpart, it is heavily implied that the Darkness is not the Element itself, but the concepts that people have: If the Darkness wins, the Light will forever be extinguished, and the universe will be plagued with eternal torment.
 *  Evil-  Anyone is capable of developing a heart devoid of good.
 *  Death- An absolute disregard for all of life.
 *  Destruction-  Some people just want to see the universe burn.
 *  Negative Emotions-  Hunger for power, lust, and so on.
 *  Hatred-  It is as dangerous as it is powerful, because one can be completely consumed by it.
 *  Nihilism-  Life is absolutely without meaning, at least to some individuals, and to end its "suffering" is to kill everybody and everything.
 *  War-  Like a wildfire, war can spread across the cosmos, thus being one of the most primal concepts there is.

Trivia

 * The Light and the Darkness appear to be based loosely on the personifications of Jesus and Satan respectively.
