It had been 3000 years since the planets left and became rogue planets.. and Earth has, changed, he isn't cruel, just different, more closed off, too.. and Luna, he's colder now, still acts the same with Earth, bc they're brothers, but acts colder and more snappy with people who aren't Earth or Sun. Sun is, different, less chaotic, & has dyson rings (I think they're called that) around him to collect energy. Sun and Earth had become alies, and by some weird science stuff on the humans part, they added enough gas & mass & water to Sun to make him a white giant, without him going boom. The humans had also changed, now they're almost a type 3 civilization, yet now they treat planets with respect and only colonize planets who agree to it. (Also they somehow managed to colonize Luna, idk how, so now Luna has a ring around him to keep his climates stable due to him being tidally locked with Earth) And the humans have also managed to use materials from the Oort cloud, Kuiper belt, & Asteroid belt to create new planets for the Solar System. Now the humans are trying to spread to other Star Systems to spread "order", Sun does it to prevent other stars from having their planets taken away by the rogue planets, and Earth does it so no one else gets abandoned like he was, Mars broke his promise.. he didn't come back..
