Nihilantis, Sun of Yata
After Nihilantis returned to Timeline-002, it had entered a slow collision course with Alpha Sol, which suddenly accelerated to the speed of light to Sol, entering a extremely close orbit with one another, spinning faster and faster past the speed of light as the very matter that made up Alpha Sol was ripped apart as Nihilantis took its place as the centre of gravity for the Sol System. A massive sola rflare was shot towards Yata, prompting them to begin backing up their systems as fast as possible as their data centres and electrical grids were ripped to shreds. Jakalaika and Iujadogia began making preparations to somehow make a break for Jupiter, but it all seemed unlikely to succeed. West Malia began considering trying to extract Void Energy from Nihilantis in order to undo the Merger of Yata and Theia, which Yetia began helping with logistically.

For a year Nihilantis was the sole star in the Alpha Sol System, until one day another star rose above the horizon as a massive Blue Hypergiant had entered the system. Nihilantis freaked out as it recognized this star, so it initiated the destruction of Yata before it was too late, burning up the inner planets as temperatures reached 70 Celsius in even the coldest regions. Iujadogia and Jakalaika had seized the seemingly abandoned Jupiter Fleet and fired its weapons onto Nihilantis, who began releasing ships to fight back as it activated gravity lasers to fly out of the system alongside Yata, Corecent, and Theia trapped alongside it. Iujadogia reacted quickly and activated its own gravity lasers to try to keep the 3 planets in place while Nihilantis began nearing supernova potential. The blue star suddenly fired its own lasers onto Nihilantis, causing it to lose control while the fleet that had emerged from it escaped. Nihilantis was flung out of the system by the star, which was followed by Nihilantis going supernova and scorching much of the outer system. All planets within the Alpha Sol System were ejected except for the 3 human worlds.
Average temperatures dropped below 0 as more and more countries covered in ice while Yata and Theia finally unmerged. The blue star suddenly spoke as 'Antarios' apologised for such a long wait as its mass suddenly shrunk to the point that the 3 planets could exist at temperatures of roughly 30C, causing floods as Antarios' colour shifted to a warm orange. Antarios revealed itself to be an agent of the Red Leader sent to 'dispatch' Nihilantis for being a threat. The only thing Antarios demanded in return for its 'intervention' was the expatriation of New Asophania, Ilcadia, and Zirnec back to their dimension, prompting them to hide at Gensokyo while they were hunted for. Antarios demanded that Gensokyo hand them over, so Asophania and the others offered themselves up for capture as they had a plan to get out of this. A ship came from Antarios to go pick them up, only for them to suddenly teleported away as Asophania had a Teleportation device in their hand. Asophania, Ilcadia, and Zirnec appeared at Jupiter, where Iujadogia and Jakalaika were about to leave. Angered by the 3's disappearance, Antarios threw a 6km wide meteor at Theia, striking Grand Jalakia Island as a massive tsunami echoed across the world. Another meteor struck Yata next, slamming into the Ganges Delta. Iujadogia's ships returned which was followed by people turning pink and teleporting away, with only 50 thousand remaining on Yata, not dying even as Yata collapsed around them as they simply fell through the floor.
Theia and Corecent were left intact but Yata had vanished, though Iujadogia suspected that it still may be out there somewhere. Jakalaika noted that the 'Universal Center' had a copy of the planet in the Planetary Database held at Universalis Prime, the very centre of the entire universe. Alpha Universalis, the capital of the Universal Union Council had a special meeting regarding the Virgo-351B galaxy group, as a 'insurgent group' named Nihilantis after a star they had stolen from Andromeda had made contact with the enemy of the UU, the Red Leader. Seeing Nihilantis as a threat to the star system this happened in, the UU had made a copy of the planet "Yata" to the emergency planetary database until more details arrived. The UU's ambassador to the galaxy cluster, Jakalaika had reported that the star system was ripped apart as another star which served as an envoy of the Leader had arrived and captured the 3 main planets after forcing Nihilantis to flee. Jakalaika had now arrived at the council ahead of time while Iujadogia and Humanity were still in transit. Jakalaika spoke on how it believed that the instability caused to the local spacetime could be used by the Red Leader to get through into this dimension, therefore at least 4 Spacetime Stabiliser Crusaders were requested to be deployed alongside a supernova clean-up crew and an extraction of the copy of the system from the database. Nearly all of the 500 thousand representatives in the UUC nodded in approval. Iujadogia's ships promptly turned back once they received news that the UU was on its way to rebuild the Alpha Sol System. Jakalaika was concerned that Nihilantis wasn't really that much of a threat anymore as the danger it previously possessed was dwarfed by the possibility of the Red Leader's return, therefore it decided that it needed a new junior representative to accompany it to the UUC. Iujadogia refused, but they nominated Yetia as the best possible candidate as the Red Leader was also originally a Yetian, reasoning that only a Yetian could outwit a Yetian. Yetia was initially hesitant, but was eventually convinced into agreeing as they sent over their best diplomat to reside in Alpha Universalis for most of the time to represent the matters of the entire galaxy. Antarios had fled by this point, with wherever it ended up remaining unknown thanks to it being a rare case of a mobile Living Star.
