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 solarflare 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, Ilcados, and Zirnec appeared at Jupiter, where Iujadogia and Jakalaika were about to leave. Angered by the 3's disappeance, 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.
