The Owl House ended with season 3 after Disney surprisingly canceled the show in spite of its critical acclaim, and viewers were left wondering why it wasn't renewed. The animated series premiered on Disney Channel in January 2020. Over the course of its three seasons, The Owl House follows Luz (voiced by Sarah-Nicole Robles) when she ends up in the Demon Realm. While she tries to find her way back home, Luz resides at the Boiling Isles. She trains as a witch under Eda Clawthorne (Wendie Malick), a witch who also goes by the name The Owl Lady.
