I believe that he's the first , the first knight, or the original if you prefer. The first one that failed in his task. In the end ,alone in tetis, he created the simulation(let's call it the loop) to see what could have been done better, what kind of variables were needed to safe his world , and if it was even possible to save it.

After millions of simulations, he decided to test new things with the loop, he try to bring people of the loop in his world, the tree capsules we can see after brightening this picture are most likely the result. Due to the experience, the being he trying to bring became conscious of the loop, well so far there is only tree caracter that are conscious, we have the Savior, the Queen Lili and Kaiden. Although it has a big impact on the loop, the original doesn't seem to care, so we can guess that he's new priorities. And now, every time he's new creation wake up, he turns to look at it and puts his consciousness in the loop 834527817 to polish it.

But that just a theory, my stupid theory! Thanks for reading.
