Selene is halfway through her eighth century of life but will forever remain sixteen, in appearance. And also in mind.

Vampires in this reality are a thing; after being so long hidden in the shadows, all sorts of fantasy creatures are revealed to be existing. Some of them, even things which go 'bump' in the night. But it's not all bad; those human scientists have formulated a 'cure' to take the bite out of so many creatures ― and, for those who resist, or are too much for the 'normies' ... there's Solitary.

Having undergone some number of centuries kept within the Solitary block, Selene is once again out in the world. But since she first went in, a large number of things happened to her: summoned to another world and had her race changed to an elf, becoming a hero for a kingdom in that world, and given birth to a number of children too. She had people who cared for her; but also the humans hated her, and made her dead.
Then to come back 'home' at the end of it, just to be back in her cell.

Also since being taken into Solitary, Earth has changed. A lot. Like, exploring space, meeting other humanoid and other races, creating this vast interstellar community ― all of which Selene didn't get to witness. But for her time alone, she's given enough credits to start a life in this new galaxy.
