Chilling Adventures of Sabrina gears up for final battles in new season 4 trailer

Netflix is facing the end of its Sabrina fest -- and possibly the end of the world.

Sabrina Spellman and company are gearing up for a final series of battles in the new trailer for The Chilling Adventures of Sabrina part 4, out Thursday.

In what will be the last installment of this occult-heavy spin on Archie Comics' Sabrina the Teenage Witch, Sabrina and her coven of witches and mortals will have to defend their home from the Eldritch Terrors, which are some type of ancient, "world-destroying" entities, and something called the Void.

"We're at the end of all things," cousin Ambrose says in the trailer. But Sabrina has overcome seemingly undefeatable foes again and again, all with heaps of confidence and one great sweater after another.

The final season of this Netflix original drops on Dec. 31.
