Wizards vs Aliens (2012)

S2E7 The Curse of Crowe (1)

Gemma Raven, a teenage wizard, strikes a dreadful deal with the Nekross: if they spare her mother's life, she'll cast a spell powerful enough to shatter Tom and Benny's friendship for good. When Ursula gets pulled into the sinister scheme, she learns that something far worse than death is waiting for her—the horrifying Neverwas.
