Teasing a mythology without explaining it is a delicate skill, and the horror prequel series built around a famous small-town curse has just demonstrated how to do it quietly. An episode released with almost no promotion turned out to be the one that ties together threads viewers had been collecting for weeks, filling in backstory that had previously been implied rather than stated. That approach rewards attention. Followers who read the source material recognised the references immediately, while casual viewers simply got a story that felt stranger and older than the one they had been watching. The risk of releasing crucial information without fanfare is that much of the audience will miss it, and the show will have to find other ways to carry the weight later. The benefit is trust. A series that refuses to explain everything immediately signals confidence, and confidence is what separates a well-built horror narrative from one that merely lists its rules in dialogue. The decision to keep that revelation quiet suggests the producers trust the audience to follow the thread without being guided.
The irony that fans ofStranger Things, a show heavily inspired byIT, spent monthsconvincing themselves there was a secret episodeis somewhat amusing when considering that the prequel seriesIT: Welcome to Derrymanaged to drop a surprise episode on Halloween at midnight. Although the first season ofIt: Welcome to Derrytook place in the 1960s, two decades before the events ofStephen King's original novel,Season 2 is expected to go back further in the timeline to the 1930s during the Great Depression. The show's new prequel episode, a standalone installment titled “A Story of Derry,” goes back even further than that into pre-Colonial times, where the Western Wood hasn't yet been founded as Derry.
The most powerful idea inIT: Welcome to Derryis that the ancient evil doesn't take just one form, as it represents a societal danger that reconfigures itself within different generations based on the context of the era.“A Story of Derry” explains how the spirit known as “The Galloo” was first confinedto the land that would eventually become Derry, even if its evil had already caused mass destruction. A core tenet of King’s stories is the idea that there will always be a group of brave, often young outsiders who are willing to take a stand against these supernatural forces, and“A Story of Derry” features a compelling ensemble of new protagonistsin Necani (Kiawentiio), Maneese (Michael Podemski-Bedard), and Kino (Isabel Deroy-Olson), the warriors from the Shokopiwah tribe who go hunting for the Galloo.
Your instincts, your strengths, and your particular way of thinking under pressure point to one villain you actually have a fighting chance against. Everyone else — good luck.
Jason is relentless, but he is also predictable — and that is the gap you would exploit.
Michael watches before he moves. He is patient, methodical, and almost impossible to detect — until it's too late for anyone who isn't paying close enough attention.
Freddy wins by getting inside your head — using your own fears, your own memories, your own subconscious as weapons against you. That strategy requires a target who can be destabilised.
Pennywise is ancient, shapeshifting, and feeds on terror — but it has one critical vulnerability: it cannot function against someone who genuinely stops being afraid of it.
Chucky's greatest advantage is that nobody takes him seriously until it's already too late. He exploits the gap between how something looks and what it actually is.
‘IT: Welcome to Derry’ Returns to One of Its Most Important Episodes
If the Galloo and the Shokopiwah tribe sound familiar, it’s because they were first introduced inthe Season 1 episode “The Great Swirling Apparatus of Our Planet's Function,”where Dick Halloran (Chris Chalk) is working under the orders of Lieutenant General Shaw (James Remar) to interrogate the Native American teenager Taniel (Joshua Odjick) to learn about his aunt’s story about how the Galloo first came to Earth and was eventually imprisoned by their people using a fragment from the star.“A Story of Derry” offers more detail to this origin taleby telling it from the right perspective; instead of this critical piece of Native American mythology being coaxed out of a victim through militaristic interrogation, it is shown from the perspective of the young warriors of the Shokopiwah tribe who would go on to pass it along through oral traditions. Colonialism is a component of how The Galloo reconfigures itself, which is hinted at in “A Story of Derry;” not only does it first take the form of white colonizers who have impeded on the land, but it is implied that The Galloo was awakened by the military in an act of appropriating Native American magic for their own gain.
‘It: Welcome to Derry’ Creators Tease a “Very Emotional Ending” That Will Destroy You and a Bigger Three-Season Arc
EPs Andy Muschietti and Barbara Muschietti also talk about that gruesome car ride, the movie theater massacre, and holding back on Pennywise.
One of the bigger surprises in “A Story of Derry” is thatthe episode includes a great performance fromZahn McClarnonas Mativ, a Native American warrior who initially explains the story of the Galloo to Necani and their friends. The revelation that Mativ has been corrupted by the Galloo, which led him to massacre his own tribe, is a reminder of how cursed the land is to experience acts of violence that leave few survivors, allowing the stories to be lost. It’s also a showcase for McClarnon's terrifically unsettling acting, because Mativ is initially presented as being a caring mentor before revealing himself to be compromised. McClarnon does a great job of showing Mativ's complexity as the character struggles toresist the corrupting influence within him.
‘It: Welcome to Derry’ Introduces One of Stephen King’s Most Important Characters
The most shocking reveal in “A Story of Derry” is thatit marks the first on-screen appearance of Maturin, the cosmic turtle with the power to defeat the Galloo. Although the idea of an all-powerful turtle might seem ridiculous to those who aren’t versed in King’s lore, this character is of critical importance within many of the author’s most legendary texts; Maturin is one of the 12 ancient guardians inThe Dark Toweruniverse responsible for holding up the pillars of reality, and in the originalITnovel, Bill recites a ritual taught to him by Maturin to expel Pennywise. It’s been suspected thatIT: Welcome to Derrymight delve into some of the weirder aspects of King’s mythology and potentiallyincorporate aspects of some of his other novels, and the introduction of Maturin is the first clue.
Although it's an important piece of lore that provides necessary context for the series,“A Story of Derry” is alsoa thrilling standalone installment that revamps the story from a fresh perspective.IT: Welcome to Derryis at itsbest when it moves beyond ties to the original noveland goes deep into Derry's history, and hopefully more episodes like this one will take similar risks.
