Los Angeles, California - The beginning of the end for Stranger Things has begun as the show's writers confirmed that work on the final season is underway!

Just when viewers thought it was safe to breathe again, the Netflix series revealed on Tuesday that writing for the big finale has already started.

The official Twitter account for Stranger Things writer's room posted a tweet with a snap that showed a whiteboard adorned with the logo for the final season, along with the caption, "Day 1."

Stranger Things, meanwhile, is also on its final lap. Season four of the Emmy-nominated series, which was split into two volumes, ended with a gut-wrenching cliffhanger as one of the main character, Sadie Sink's Max Mayfield, was killed by the new baddie Vecna, played by Jamie Campbell Bower.

Thanks to Millie Bobby Brown's Eleven, Max was brought back to life, but has since been confirmed to be brain-dead.
