The series had just won an Emmy
'The Dark Crystal: Age of Resistance' will not be returning for a second season on Netflix.
The fantasy puppet series was a prequel to the 1982 film 'The Dark Crystal'.
A star-studded cast loaned their voices to the show, including leads Taron Egerton, Anya Taylor-Joy, and Nathalie Emmanuel.
Other members of the cast included Caitriona Balfe, Helena Bonham Carter, Natalie Dormer, Gugu Mbatha-Raw and Mark Strong.
Alicia Vikander, Mark Hamill, Jason Isaacs, Keegan-Michael Key, Simon Pegg and Andy Samberg were also among the supporting cast.
Set in the land of Thra, the show depicts how a group of young Gelflings discover that the evil Skeksis plan to consume their kind through the dark crystal to give them prolonged life.
The show won an Emmy for Best Children's Series just last weekend.
Exec producer Lisa Henson confirmed the news to io9.
She said: "We can confirm that there will not be an additional season of 'The Dark Crystal: Age of Resistance.' We know fans are eager to learn how this chapter of 'The Dark Crystal' saga concludes and we’ll look for ways to tell that story in the future.
"Our company has a legacy of creating rich and complex worlds that require technical innovation, artistic excellence, and masterful storytelling.
"Our history also includes productions that are enduring, often finding and growing their audience over time and proving again and again that fantasy and science fiction genres reflect eternal messages and truths that are always relevant.
"We are so grateful to Netflix for trusting us to realize this ambitious series; we are deeply proud of our work on 'Age of Resistance,' and the acclaim it has received from fans, critics and our peers, most recently receiving an Emmy for Outstanding Children’s Program."
It is unclear at this time exactly why the show was cancelled.
One source claims the series was an "expensive disappointment".
You can stream season one of 'The Dark Crystal: Age of Resistance' on Netflix now.
