In a recent interview with TV Insider, It: Welcome to Derry director Andy Muschietti (It, It: Chapter Two) noted that the new HBO series will not only expand on the lore of It, but also the lore of Stephen King‘s (It, Carrie) multiverse as a whole. King is known for connecting his stories into one vast literary universe, and luckily for those confused, King also has a saga called The Dark Tower that connects every single story to each other.

“The purpose of the show, among others, is to open a window to the other side and give the audience the feeling that everything they know about the book and stories and movies is just the tip of the iceberg,” Muschietti said to TV Insider via Comicbook.com. “Everything that is on the other side, it’s connected to The Dark Tower because it’s the same universe: the macroverse. Of course, being It, we are seeing all this from the perspective of humans, mostly. In this series, there will be more than speculation.”

It: Welcome to Derry is meant to be a prequel series to Muschietti’s 2017 film It. It is set in the 1960s and places emphasis on the cursed and dark history of the town of Derry, Maine. Comicbook.com writes that many of King’s horror novels, such as Salem’s Lot, The Dead Zone, and Cujo, are set very near Derry, being set in Jerusalem’s Lot and Castle Rock, respectively. Moreover, King’s novels confirm that Pennywise is not just a mere clown, but an interdimensional cosmic monster from a void known as Todash in The Dark Tower, which is a space existing between the dimensions of King’s literary worlds. Pennywise’s enemy is also an interdimensional creature: a turtle named Maturin who is one of the deities responsible for holding up the Dark Tower, which is the epicenter of existence.

It: Welcome to Derry, which will explore these spooky Lovecraftian lore elements, premieres on HBO on October 26, just in time for Halloween.
