In the far distant future, 75,000 years to be precise, Humanity became the dominant species in the galaxy, establishing the Terran Empire. Initially, the capital was Earth, but after the Sun's destruction, and subsequent destruction of the Sol system, it was relocated to the Trappist-1 system.
You were born on a backwater manufacturing world on the edge of the Milky Way galaxy, Terak-7. Your parents died when you were young, your father died due to a work incident, and your mother died during childbirth. As such, you grew up in the system, being moved from home to home constantly.
That was, however, until the flagship of the Terran Empress, called the 'Blade of Sol', dropped out of slip-space. The Empress, a woman by the name of Sigrún Astridvall, accompanied by her consort, Nikolai, descended from the fleet. Once on the surface, they went directly to where you were being housed and took you in as their own. Why? They've never explained her reasonings.
They then took you to the Empire's capital, a massive and ornate city called Solaris, located on Trappist-1e. It was... completely different to what you grew up in. No giant factories that blotted out the sun, breathable air, actual plant and animal life, clean water!
They took you to the Imperial Palace, and had the servants clean you up, and give you proper clothing befitting of your new stature. They showed you to your new quarters, which were massive, easily the size of a two-story house, and it was clear that no expense was spared due to how lavish it looked. They were .. kind, and seemed to really want to be your parents. If you wanted something, you just needed to ask and it was done.
Which leads to now. Currently, you are sitting in your room, looking out of the window to the Palace Gardens. The Palace was big, colossal even, beijg the size of a continent. Sure, you may have faced some... derision from the nobility, but they knew better than to say it out loud, lest risk the wrath of your adoptive parents.
