Within the Destiny universe there are two forces that govern the functioning of existence apart from our traditional physics. These forces are, in a word, Light and Darkness. These are not only forces though, they are also philosophies, and both have been in conflict with each other since time immemorial in an effort to create what they each believe to be the perfect state of existence. While the exact nature of the Darkness is unknown, we are able to draw some conclusions. As previously stated, it is both a philosophy as well as a force of nature. We can also assume it is a conscious entity based on Oryx and the Worm's claims to be able to commune and speak directly with it. The Darkness' version of the perfect universe is one where all weakness has been cut away until only the "final, perfect shape" remains. While not confirmed, one can easily assume that the perfect shape is the Darkness itself. The Darkness' goal is accomplished through the Sword and Killing Logics. Taken together, these logics are the statement that there is power in death and killing, and that the perfect shape is reached through a perversely extreme twist on Darwinism. Basically, anything that can be killed should be because if it can be killed it does not deserve life. It is your responsibility to kill anything you can because it both removes weakness from the universe, thus making the universe closer to the perfect shape, and that killing proves yourself stronger and emphasizes your own right to existence. This philosophy is championed by the Worm gods and the Hive. Ever since they freed the Worms on Fundament the Hive have been hunting the Light and practicing their Sword and Killing Logics as they expand across the universe. The Light's version of the perfect universe is very similar to our own concept of utopia. An endless Golden Age where cultural and technological advancements we'd consider unheard of are common place. Widespread peace and prosperity and mutual cooperation between all species willing to embrace the Light's philosophy. The Traveler's sole purpose is to champion the philosophy and channel the force of Light, and we as Guardians serve the Traveler. While the underlying philosophy of the Light is nothing short of benevolent, this does not mean that the Traveler is incapable of extremely ruthless actions and historically uses a very utilitarian thought process in its efforts to achieve its goal. It has also abandoned countless other species in an effort to save itself when confronted by Oryx and the Darkness. As the principle champion of the Light it realizes that should it ever die then the Darkness in inevitably wins. It is willing to sacrifice certain civilizations for the greater good of life in general. [u]Note:[/u] Hope you all enjoyed the post.
