happy sol day!! i headcanon sol as a gay trans tom, and him and blackstar as mates (who have a dramatic breakup lol)
No joke, toxic Sol/Blackstar strangers to lovers to enemies is what happens in Cloud!Three. (The AU where Leafpool and Crowfeather leave and run into Skyclan, making Cloudtail and Brightheart's second, now little born sooner, the Kin of Firestar's Kin.) Russetfur dies and Sol encourages Blackstar's bad habits, getting into a relationship that sees Blackstar backslide towards his Deputy Blackfoot days...
I've got WCR!Sol as gay ace, but as one of the very rare amab tortoiseshells! A little copy of his mama Cinders, only darker, where her fur is lighter, more sun-like, where Whispers is pitch-black with a broad, bright white face, being moon-like.
He's a mysterious character in WCR, with his origins being much different and his outcome being much spookier.
