The final season of Stranger Things is going to deliver — or, so says the cast.

In a new teaser for season 5, stars including Millie Bobby Brown, Winona Ryder, David Harbour, Joe Keery and Finn Wolfhard reflected on the final season, from the emotions they felt on set to how the story gets even bigger before it wraps up.

As the teaser begins, co-creators Matt and Ross Duffer reflected on how they’ve tried to capture the “magical” quality of childhood in the series, as Ross called that feeling “the heart of the story of Stranger Things.”

Harbour, who plays Jim Hopper, adoptive dad to Brown’s Eleven, then recalled thinking the show’s pilot episode was “one of the best pilots I’d ever read.”

“It felt so pure and just beautiful,” he said.

When the show premiered in 2016, and Brown, Wolfhard, Noah Schnapp, Gaten Matarazzo and Caleb McLaughlin were all between the ages of 10 and 13, Schnapp said they were “just a bunch of random kids from different places that just loved our characters. We loved the story.”

Charlie Heaton and Ryder, 53, similarly remarked on the near-decade since the show’s premiere, as Heaton said the cast has “grown up as a family,” and Ryder said watching the cast grow up was “the biggest gift that this show has given me.”

Despite how much time has passed, Matarazzo, 23, said of their bond on set, “As exciting and grand as we always seem to get, season by season, it still feels like the same group of nerds from the first season.”

Turning their focus to what’s to come in the long-awaited fifth and final season — which comes over three years after season 4 premiered — the Duffer Brothers once again teased that it’s “the biggest season we’ve ever had — in terms of action, in terms of visual effects, in terms of story.”

“Ultimately, what people want is — they want to see these characters together one last time,” Matt and Ross said.

In Brown’s words, season 5 is “more of an adventure and more of a mission, which I really like.”

“Everybody is really put into the thick of it. No one is sitting back on a walkie-talkie,” she teased. “Everyone is full throttle, going for it.”

As the teaser ends, the cast doubles down on their teasing of what’s to come.

“It’s the highest stakes that the show has ever been,” Wolfhard, 22, says, while McLaughlin, 23, adds, “We’ve come full circle. The fans will be truly satisfied with the ending.”

Filming wrapped on season 5 in December, and Brown, 21, was emotional on set as she read the cast and crew a heartfelt letter to say goodbye. She later admitted she was “not fine” on the last day on set, as she said on the Today show in March, “I kind of was like, ‘Oh, I’ll be fine, I’ll be fine, I’ll be fine.’ And then I think it was a defense mechanism, I think it was my coping. And then I realized I was not fine. I cried a lot.”

Brown has encouraged fans to “be patient” as they await the upcoming final season.

“Let the Duffers create what they’ve been doing for the last 10 years so beautifully,” she told press, including PEOPLE, in February. “It is worth it, I promise.”

Stranger Things season 5 premieres with Volume 1 on Nov. 26, Volume 2 on Dec. 25, and the finale on Dec. 31.
