When the universe is threatened by the rise of Zarkon and the Galra Empire, six strangers are pulled into a battle they didn't choose-but one they're destined to fight. Kassie Noel Kogane (or just Kass), half-sister to Keith (same father, different mothers), never imagined she'd be part of something cosmic. She's tough, sharp-witted, and still mourning the quiet strength of her Altean mother, Athena, who raised her on stories about stars, instinct, and hidden truths. But everything shifts when Kassie is chosen by the Purple Lion-a legendary and mysterious component of Voltron with the unique ability to replace any missing Lion in battle. As she embarks on this journey, Kassie begins unraveling a legacy buried deep in her bloodline: fragments of Altean heritage, mystical power she barely understands, and visions that tug her toward Voltron's forgotten past. While bonding with her Lion and confronting shadows from her family's history, Kassie must learn to trust herself, lean into the wisdom passed down through generations, and fight beside the very people who now call her a teammate-including her brother. Together, they're more than soldiers. They're Paladins. And Kassie's rise may be the key to Voltron's future.
