The alliance between the Light and Dark Realms or Kingdoms as many others would say was not always peaceful. The Human world, Earth, was plagued with death and despair as the Light and Dark were trying to gather souls to make their Kingdoms stronger. When the God of both kingdoms saw that the Humans were dyeing too early for their time and the two kingdoms were becoming too greedy for the souls he decided to put forth two people who would rule the worlds for him. He made Lord Halcyon the ruler of the Dark and Priestess Aurora for the light. To make sure there would not be a war between the two Realms again he made them sign a treaty.
“Must we sign this treaty? The point of putting two rulers is so the Dark and Light do not get out of hand.” Lord Halcyon said in a puff of frustration. This was so annoying, he hated the light and hated that God was making them do this.
“We are doing this so there will be peace amongst the two realms. We do not want a war between the two do we, Lord Halcyon?” Priestess Aurora asked with a smile.
Halcyon sighed; the damn woman herself was annoying. Too much light and brightness in her voice itself, “No of course not Priestess Aurora.”
“Alright, the treaty has now been signed between the Light and Dark Realms. There will be peace amongst them as long as neither side interfered with human affairs. Neither side is allowed to involve themselves in human wars, politics, entertainment, scientific discoveries, ECT… Light is not allowed to kill Dark as is the same for the Dark. If either Light or Dark aligns themselves with humans in any way their citizenship in their aligned realm is revoked and is now a citizen of Earth and is to be considered human.”
Lord Halcyon interrupted, “So we are to have nothing to do with the humans at all?”
“Correct.”
“May we protect them, God?” Aurora asked, she was still young and was not sure of the parameters of the rules.
God paused, “What do you mean by this question child?”
“Well, we are to make sure neither side kills a human without it being their time correct? So it would seem that we would need protectors in case either side decides to rebel. I am only trying to make sure if there is a worst-case scenario the humans do not pay for the stupidity of the Light and Dark affairs.”
God smiled, for a child, the girl was mature and thought things through like a Priestess should, “I now understand where you are coming from my child. What do you propose for this idea of yours?”
The Priestess thought, “Well in many myths there are beings called Valkyrie, they are known for taking souls. Should we not make it fitting that Valkyries are the ones to take the souls of humans? These must be trustworthy beings; they are the only ones who are allowed to kill the Light or Dark…”
“Wait! These cannot be humans so they must be light or dark. Who chooses who the Valkyrie will be?” Halcyon only liked the idea if it would favor him. He did not want the light poking around in his business.
“Would you let her finish her idea Lord Halcyon, you may finish child.”
“Thank you, as I was saying they would be the ones who were allowed to kill the Light or Dark if they begin to rebel. It would be a sort of task force, the Light would pick trustworthy beings for themselves and the Dark would do the same. Now they are the only ones allowed to take human souls, kill rebelling Darklings or Whiteling. This would then ensure equal responsibility, further the peace, and ensure human souls are not taken before their time.”
“I believe that is a wonderful idea Priestess, what do you think Lord Halcyon?”
Halcyon really couldn’t go against God even if he didn’t like the idea at all, “It seems like a good idea.”
“Well, then I shall add it into the treaty. Furthermore, when the humans die their grey souls must choose Light or Dark, after their choice they will choose to either be reborn into the world again or remain in the realm itself; if either side interferes in any way the penalty is death by a Valkyrie. If either side decides to revolt and chooses to ignore the Treaty set forth it will mean the end of their race. Also, light is not allowed to have relationships with Dark that would bring forth a child.”
Halcyon laughed, Aurora was a bit puzzled. The thought of the two races being together seemed impossible, both sides seemed to completely hate each other.

It was later foretold by an Oracle of Light and an Oracle of Dark that one day a warrior of Light and a warrior of Dark would align together to create forever peace between the two Realms. After this Lord Halcyon killed every Darkling and Whiteling that aligned together to make sure that the future never happened, this brought the war between the two Realms. Halcyon soon aligned himself with forces and magic that made the Darklings much darker and for himself, more powerful.
