All worlds connect, no matter how distant or how small, at one central point. For time immeasurable, that place lay forgotten by all; unclaimed, torn, wrought barren by fluctuations from the different realities that encroached upon it.
Eventually, there were those who began to notice just what power lay within such a place. These individuals sought that power for themselves and set about to try to control it. They unleashed a horrendous disaster that rippled through the multiverses, nearly destroying many realities and worlds.
Then came the Three: Love, Mercy, and Life.
They were neither mortal nor immortal. Those who witnessed their power called them Divine. These beings, who transcended all that was known, were angry at the selfish behavior of those who had nearly eradicated Life.
So, the Three took over the Nexus and forbade the would-be conquerers from ever basking in that glorious power again.
These Deities watched over that place and kept it safe for so long. They worked in unison, none taking more control than their two companions, and it eventually flourished. It became habitable, stabilized by their power.
Unfortunately, after a time, these ageless beings started to become idle and a boredom that only such creatures knew clawed at them with lonely fingers.
The First, he looked upon the lands they held and told the other two that it was lacking passion and love.
The Second, she looked upon the lands and sighingly agreed. She had been the first to become so utterly apathetic.
The Third gazed upon what they held with her wise eyes and agreed with her companions.
We are slowly being forgotten, my friends, the First said. If something isn't done, all that we have tried to do will be for nothing.
What can we do? asked the Third.
The Second, who had been giving this entire matter much thought, finally put forth the idea she'd been entertaining for only she knew how long.
Eventually, we will lose our power and be unable to keep this place safe, she said and her brethren agreed. I propose this; let us open some of the paths from the worlds beyond and populate this place. If they come to see it as a home and haven, those who find their way here will defend it more effectively than we.
I think I like this idea, said the First, who looked to their silent companion.
I do, as well, the Third said and gazed off in the distance of the worlds beyond. I believe, I know just the thing to make this happen. Allow me to procure us someone who will represent our... interests. Is that agreeable?
The First and the Second nodded.
We leave it to you, my Lady.
