As for Efim'ia, she's Aurorean royalty, second in line to the throne after her oldest brother (an NPC). She has a younger sister, vulgar who ended up going missing for a period of time. Mia joined a crew of elite space pirates to look for Hecate and found her on Earth, captured and being experimented on. When she was a space pirate, she was very Star-Lord-esque. She used the alias, Quartz, and was notably immature, silly, and wild. Finding Hecate though changed her life. Mia rescued her sister and others like her and at first, simply opened up a mansion/safe space. This mansion, only reachable via a portal, eventually became the Vega School -- similar to Marvel's X-Mansion/Xavier's Institute. I'm admittedly still fleshing out her timeline and the school's details! But so far, this is what I have on her! I want to say Mia landed on Earth around the 80s?
