The recent episodes of Stranger Things have unveiled a significant twist regarding the nature of the Upside Down, revealing it to be a mere passage to a more sinister realm known as The Abyss. This new understanding comes as character Dustin uncovers information from Dr. Brenner’s notes, suggesting that the true source of evil, including the Demogorgons, originates from this alternate world rather than the Upside Down itself.
Creators Matt and Ross Duffer disclosed that this concept was established nearly a decade ago, during the show’s inception. They detailed a comprehensive mythology document that explored the origins of the Upside Down, initially referred to as Dimension X. The showrunners were intent on maintaining an air of mystery throughout the series, which led to extensive discussions about the backstory, despite Netflix’s requests for clarity.
This revelation marks a pivotal moment in the series, with the Duffers expressing relief at finally sharing this long-held secret. The latest volume of the show, which recently premiered on Netflix, continues to build upon the intricate lore that has captivated audiences since the first season.
