"For a long long time when the solar system was very young, only the elements of space existed. It wasn't until a great energy developed into Life, that the gods began to come into existence. Life was the first goddess. She found earth, and over time molded it into her greatest creation. Out of what she created however, came Death, for what is living that is not a god, must one day be gone, or be reused. The two of them presided over Earth alone, watching as it evolved. It was not until the realm below earth birthed a new goddess, Demon, that they payed any attention to what was developing above and below them. Through Demons existence and the universes law of Balance, the upper realm too generated a being of its own. It called itself Angel, and he was Demons counterpart. All of these realms were quite similar to one another. They all held life, they all had a guardian, but some of the guardians did not get along. Angel and Demon failed to see eye to eye, and sometimes, Life and Death could not get between the two to stop them from fighting.
Eventually, the four guardians made an agreement. Demon's realm, the least naturally populated, would be the home of remaining souls. Every so often, a soul would be put back onto the middle realm to live again, unless it had become corrupted by the malevolence. Souls that became corrupted would be destroyed. Some while they were on the middle realm through Death's attempts to keep the humans safe, and some that had not gotten to the degree of malevolence to be of his concern but we're not suited to be reused, would be destroyed by Demon herself.
Angel came to fear the power and usefulness that Demon had over him. His realm was not used for anything. He was always weaker than Demon and the others were because he had been created from less energy than everyone else had been. To protect himself, fueled by his paranoia, he created a barrier, blocking himself and his realm from the others. Eventually, this caused a similar one to be created barring Demon's realm. Angel's distrust soured his relationships with the guardians. And they have never done anything about it, letting the rift remain for all this time."
"Mom, why haven't you guys ever made up?" asked Akira, lying in bed.
"Because sometimes, after someone has done you harm, you don't want to make up or forgive. It takes time and effort, and sometimes you don't see the other as being worth that time and effort."
"Well that isn't very nice." Akira pouted, about 7 years old in Demon age.
"Not everything in life, or within our family is my child." said Lady Memoria sadly.
Akira woke with a start. Their mom told them of the creation as a bedtime story all the time. At one point they had asked why she couldn't be involved the others anymore and why, if she said that they should all forgive each other, she didn't try harder to reach them.
All she did was tell you that you might understand more when you were older, and that she would tell you the story of the Rift then.
Before then came, Akira was sent away with a one way ticket to Death City.
They couldn't shake the feeling that pent up emotions from events that caused the Rift were behind what was happening now, no matter what front they had disguising it.
