Fan Casting River in Trans Wizard Story

Karina's oldest child, who was outed to their mother against their wishes and forced to stop transitioning. She's continually used them to promote the harms of accepting trans youth and claims she saved her beloved child, but truthfully, Karina treats them terribly: they're not allowed to have any dissenting ideas form her about themself and who they want to be, and if they dare to speak out against her... Well, the things she's done to them are better left unsaid. They want nothing more than to break free of their mother's abuse, and maybe the right hand can help pull them out... Teenager. Trans VAs only; nonbinary VAs are especially preferred.
