Astarte's history

Before anyone asks, no, I did not make her up. Yes, Sailor Astarte is a canon sailor soldier. She's not in the original manga or anime, but she's a creation from the Seramyu musicals. Most of the history presented here is history from the two musicals she appeared in, Kessen / Transylvania no Mori - Shin Toujou! Chibi Moon wo Mamoru Senshi-tachi and its revision, Saikyou no Kataki Dark Cain no Nazo. Her history (and subsequently a bit of the backstory of the Miyuki musicals which helps supplement her history, as well as a bit of head canon to make sense of some things) I pieced together as best as I could below.

Astarte's alternate/possessed self, Dark Cain, has an account at cainthedark.
