Stranger Things season 4 is not coming until next year on Netflix. The series resumed filming just recently after production was halted earlier this year due to the COVID-19 outbreak. Now, cast and crews have been sharing updates on what fans can expect in the next chapter.

For instance, Stranger Things season 4 will be introducing a new mysterious group. The Twitter page of the series shared photos of the official logo of the "Hellfire Club," which is also the title of the premiere episode. The pictures give fans a deeper look at this new mysterious group.

A demonic face, which is placed below the Hellfire Club text, can be seen in the logo, along with polyhedral dice. This seemingly suggests that this new mysterious group is related to Dungeons and Dragons. In a slow-motion video, Gaten Matarazzo (as Dustin) is waving the club's flag, as well.

The series has expanded its plot over the past years while still sticking to its original theme. While introducing Hellfire Club is unusual at this point, the group's arrival means more surprises are coming. It also makes sense to bring something new since some other groups are moving out of Hawkins.

It should be noted that the exact nature of the Hellfire Club remains unknown. But, while the name sounds ominous, Dustin's potential involvement in the group could make it innocent than it seems. This could be a new name for their group in Stranger Things season 4.

Dustin, Mike (Finn Wolfhard), Lucas (Caleb McLaughlin), and Max (Sadie Sink) were the only ones left in Hawkins. They probably renamed their gang into Hellfire Club now that only a few members remain in town. In addition, this could mean a split perspective in the next chapter.

The upcoming episodes could focus on Dustin and the gang, while others focus on the adventures of Eleven (Millie Bobby Brown) and Will (Noah Schnapp). Despite being apart, everyone will eventually reunite as some episode titles hinted at their future.

Aside from the Hellfire Club, Stranger Things season 4 teased more about the Upside Down. The series has been featuring several references and callbacks to the iconic 80s film, but this story wasn't entirely addressed. The new installment could, finally, incorporate time travel.

Meanwhile, there's no need to worry about the future of the series. In an interview with The Hollywood Reporter series creators Ross Duffer and Matt Duffer confirmed that the fourth installment won't be the final one of the sci-fi horror drama.

Stranger Things season 4 is premiering in 2021 on Netflix.
