Sabrina undergoes quite an adventure, starting with unlocking the gates of Hell to rescue her boyfriend Nick and trap her father Lucifer into another body. To ensure that Hell doesn't take over Earth, she competes in the Unholy Regalia and has to simultaneously protect Earth against the pagan witches who want to claim it. When the competition goes awry, she's trapped in Hell for eternity with Lilith and Lucifer . . . until future Sabrina comes in saves her.
When Sabrina returns to Earth and realises the pagans destroyed the planet, she finds Ambrose and together they find a way for her to time travel to reverse the apocalypse. After creating another timeline, she and her clone split up their responsibilities to both realms to keep the peace, but they may have irreparably damaged space-time continuum.
