Get ready to reenter the world of Thra.

Netflix has released a teaser for "The Dark Crystal: Age of Resistance." The upcoming series is a prequel to the 1982 Jim Henson film "The Dark Crystal," and it follows three Gelfings as they go on a epic quest to save their world.

The teaser shows off a gorgeous fantasy world inspired by Henson's. It's home to the trio of Gelfings at the center of the story: Rian (Taron Egerton), Brea (Anya Taylor-Joy), and Deet (Nathalie Emmanuel). They discover a horrifying secret in the series, and the teaser shows Deet being introduced to the Darkening.

"Deet, all Thra is at risk," we hear in the teaser. "The Darkening corrupts everything it touches."

She doesn't know what the Darkening is -- but she soon finds out. Watch below.

The cast also includes Mark Hamill, Helena Bonham Carter, Andy Samberg, Natalie Dormer, Gugu Mbatha-Raw, and more. "The Dark Crystal: Age of Resistance" arrives on Netflix on Aug. 30.
