Since I intend to keep writing more Star Knights, I thought it'd be handy to have a reference for who they are, and where they've appeared.
Stories:
The Night's Own Star
Magical enby River discovers kink through a villainous encounter.
Part 1 (18+) - Part 2 (18+) - Part 3 - Part 4
The Star Knights are:
Title (name) - pronouns, blurb #transformation color
Polaris (Wendy) - she/they, leader of the Star Knights #16ebfa (light blue)
Antares (River) - they/them, sexually entangled with a villain #a13122 (red)
Deneb (Amanda) - she/her, youngest Star Knight #3d4191 (deep blue)
Castor (Willow) - xey/xem, Polaris' reliable right hand #3d913d (green)
Vega (Everett) - he/him, [description to follow] #ed931c (orange)
Spica (Spica/Spike) - it/its, known chaos gremlin #dfe630 (yellow)
Yes, they are all trans.
Other Notables:
The Night Mistress (Lauren Herschel) - she/her, kinky villain who does it for the fans
Candy Ranger Peppermint (Pepper) - she/her, a very forward girl with an interest in Amanda
