To say that we have existed since the beginning of time would be inaccurate. We always existed, before, during, and after time. Some would argue that we are existence in itself. A strange query, as we have never considered preservation of self over preservation of existence. Indeed, fate has required our self-sacrifice several times over to prevent the Undoing, and we were never hesitant to do so. Many have become aware, regarding the edges of reality as a child considers a toy. Reckless curiosity and heedless care. And we have stopped them.
Things are different now. None have come this close. Entry to our realm, to us a sheer impossibility, was never considered by us. Yet here was a corporeal form, forcing entry into a realm we assumed was secure. We questioned it on its presence, its existence, and other matters. The man, as he called himself, used words we had not heard in millennia, words that had become deaf to us. Science, time travel, innovation, revolutionary. Our understanding was limited so we were forced to make him one of us. Unfortunately, his kind had not discovered the secrets of ascension as others had, and he passed into nonexistence. Through what remained, we learned much of this life form, the Human.
What we learned worried us. There have been other life forms who have made inquiries into our realm, and who have later joined us. These humans were different. They did not seek to join our realm. They sought to rend it, to manipulate it, to bend it to their will. They had many fantasies about what they could do once our realm was under their control. They failed to realize what implications their fantasies had. Did they not realize that their tampering with reality would cause the Undoing? At the same time, we realized that there was something else unique about them. While some sought to rend tears, some sought to mend them. We learned of noble sacrifices not unlike our own, made for the betterment of mankind. They were feats we have never seen in all of existence.
Our decision was made. For the safety of these Menders, the Renders would need to be defeated. We retraced the memories of the human and returned to his origin, where his own world existed. The other humans were surprised to see us. We had inhabited the shell the human came in, and they undoubtedly expected the human within to return as well. We deciphered their language with ease, thanks to the human who met us. The humans around us grew in number, several armed with what the humans named "guns". It was clear they perceived us as a threat, the byproduct of a failed experiment. These Renders sought to eliminate us.
We had thought ahead. The vessel came with armaments of its own, and our higher existence had given us abilities greater than most humans. The Renders were eliminated swiftly. These humans, we realized, were the first to attempt entry into our realm, in a feeble attempt at time travel. Their actions were dangerous, and necessitated their elimination so as to prevent the Undoing. Undoubtedly there would be others, Renders and those tempted to break the boundaries of reality. Still, we remembered the existence of the Menders, and those who sought to fight for good. We would help them with their insignificant trifles, and they in turn would help us save are universe.
We are Psi. We will avert the Undoing.
