Something nearly slipped my mind, and then I ended up with more clues to the disappearance of the Zenussian people. Apparently, I single-handedly excavated what appears to be a very large, elliptical ring of runic summoning rocks within minutes, encased in small circles of protection light already there, unlit but ready. I counted 108 of them in a neatly arranged pattern of 27 per quadrant. This is what they think mathematically as a summoning ring of their grandest archaeological achievement, a natal calendar of sorts based on the passage of their seasons. However, the planet is already very arid, it does not have any seasons, but they used to remember it in its heyday. I then ask the dream concept two important questions, the legality of its use, and what purpose it serves. The responses are nerve wracking. It details the purpose of the summoning through every 108 years according to the amount of time it has passed since the creation of anime itself. The secretive council behind the making of such a structure wanted to bring forth exactly 108 young girls ages 8 to 21 physically that we are already familiar with over these years, wearing all black on their main apparel. They go as far as to dye their whole hair black with exceptions such as eyes and accessories. This is simply to eliminate the possibility of changing hair colors at inopportune times meant for mourning the dead. There's even a sundial acting as some sort of a device, a prediction one not unlike the one that can predict eclipses.
The girls in question being tasked by the secretive council during their prime years is that according to their natal birthday given by their respective creators must stand in the correct circle of runes facing the sundial, parallel to someone on the opposite end. For example, if someone is born on the first day of a calendar year, then it must stand at the winter quadrant's beginning circle, clockwise from west facing east with a slight degree off center. Once all its 108 participants gather at these runic circles, they make a random prediction of a world destined for heralding an accelerated growth rate of a star that would bring its early end, to warn its people of impending alien invasions using the time-traveling sundial device. The chanting process takes a relatively short time, but the actual prediction itself can take about a few hours to complete.
When a world is deem chosen for their untimely doomsday, very slowly overtime they will make the time travel journey to that world, with no ill effects. The first signs of them approaching is a few odd changes in the sky gradient, the second sign by slight orbital turbulence in a planet's orbital path which then causes the planet to move inward to its own star, no matter how far away it is, endangering other planet's orbits. The third sign after that would be changes in demographics mainly by gender ratio, marking their impending arrival, the fourth sign would be increased luminosity of its environment to fit with their surroundings, making it pretty in the short-term but with devastating long-term effects, and the last sign would be a rapid transition of a star's age. This makes it look like they are a doomsday cult with some quasi-heroic ideals, as they all need to be pure in body and soul yet can keep their original personality and appearance choices, proportions matters more importantly than their looks alone, that is what makes them unique. After all five signs have passed, they will then arrive in full swing and perform heroic feats against any world-ending threats it would impose, replace old governments with something better or if there is no alternative option, then outright decentralize it, often through violent means, and then rewind the space environmental damage but not the accelerated passage of time. Fortunately, it only so happens that often in fiction that we would not even get to see them doing this.
Assuming that anime in itself first came into fruition in 1906 with only a four-second piece of low-quality film, the same year that San Francisco got hit by an earthquake, then already one cycle was completed. Yet they were unsuccessful in their first and only prediction and thus it backfired so severely that Zenussia itself must have experienced their worst global drought in six years, causing its entire population and the girls involved to vanish without a trace, with the sundial still intact. They supposedly want to predict an otherwise healthy candidate that we been going after since Carl Sagan's Contact book, the world of Alpha Centauri orbiting three stars; two are well known because of their distance, which is also the likely setting of Avatar. Before each prediction, a single long gauntlet match of 16 potential choosers battle each other in a rundown church in its own wonderland dimension meant for that purpose simulating the passage of time, requiring the sacrifice of 108 non-organic bodies only using melee weaponry, which isn't very easy regardless of techniques, it is perseverance. If the demand succeeds within one life, then that chooser gets to be its hero for leading the prediction efforts and thus save its own world from their untimely doom with them, and if successful, can enjoy a temporal victory party before they all must return to their dimensions of origin for the next cycle. The ancient runic language is slightly longer than the English alphabet with the infinity symbol as a starter letter; they must have known most of the trending urban legend creatures that define themselves even further.
Right back to the first question towards the dream, this makes it illegal in most other alien worlds, but not the case for Zenussia. This is likely because they seem to be worshiping both the sun and the underworld that the council at the time of that prediction is loosely bound to their doctrine. Their ancient writings from the excavated site give a definite clue. It stated that when life-like worlds face extreme injustices to a point that society gives it up in making non-violent legislative changes, then their cult tries to sort it out their way through the aforementioned practices that do not involve torture but do involve fasting with immunity to starvation and sleep deprivation through sheer willpower and metabolism. Now, if only I can try to recreate the conditions of their failed prediction, set in a fictional Earth irrespective of its own timeline to see if it can produce results. I can do that easily for my favorite all-time PC game; all it takes is some carefully planned mods, a change in the game time cycle's datasheet, a texture workshop, and plenty of luck.
Unfortunately, as the dream isn't a full-fledged, vivid one yet it gave me more promising data to research, I won't post it in the dream/nightmare thread. A tad bit long for anyone to read this, but this very promising to me personally. Just don't expect me to end up making up the largest modded harem though until the very end of solving that mystery.
