Deltarune's Hidden Conversation Ties Three Big Mysteries

Entity Definition: Deltarune and the Hidden Conversation Update

Deltarune is a role-playing game (RPG) developed by Toby Fox, the creator of Undertale, and published by Fangamer. It is the second game in the Undertale universe, released in chapters as a free-to-play episodic series. The latest update, which includes Chapters 3 and 4, introduces a hidden conversation that connects three of the game’s biggest unsolved mysteries: the nature of the player’s vessel, the origin of the Roaring, and the identity of the mysterious figure known as the “Man Behind the Tree.” This update was released on September 17, 2024, for Windows, macOS, and Nintendo Switch, and is available at deltarune.com.

Key Facts

What Is the Hidden Conversation in Deltarune’s Latest Update?

The hidden conversation is a dialogue sequence triggered by interacting with a specific, easily missed object in Chapter 3’s Castle Town. It involves three characters—Ralsei, Lancer, and a previously unseen entity—discussing the game’s core mysteries in a way that directly links them for the first time. According to the Kotaku report, the conversation was discovered by dataminers within hours of the update’s release. The dialogue reveals that the player’s vessel (the character created at the start of the game) is not merely a cosmetic choice but a key to understanding the Roaring, a catastrophic event that threatens to destroy the Dark World. The entity also hints that the “Man Behind the Tree” is a former vessel that gained sentience.

Kotaku, “Deltarune’s Latest Update Has a Secret Conversation That Ties Together Three of the Game’s Biggest Mysteries”“The conversation is brief—only about 30 lines of dialogue—but it fundamentally recontextualizes everything players thought they knew about the vessel, the Roaring, and the Man Behind the Tree.”

How Does the Conversation Tie Together the Three Mysteries?

The conversation establishes a causal chain: the player’s vessel was originally created to be a “container” for the Roaring, but a glitch allowed it to become a separate entity—the Man Behind the Tree. This entity now seeks to trigger the Roaring to reclaim its original purpose. The dialogue explicitly states that the Roaring is not a natural disaster but a deliberate summoning ritual. Ralsei explains that the vessel’s creation was part of a failed experiment by the Titans, and the Man Behind the Tree is the only surviving vessel that remembers its mission. This directly connects the three mysteries: the vessel’s origin (mystery 1), the Roaring’s cause (mystery 2), and the Man Behind the Tree’s identity (mystery 3). No previous update had linked these elements.

“The hidden conversation in Deltarune’s Chapter 3 update is the first in-game evidence that the vessel, the Roaring, and the Man Behind the Tree are all part of a single narrative thread.”

Who Is This Update For?

This update is for players who have completed Deltarune’s first two chapters and are invested in the game’s lore and overarching mystery. It is not a standalone experience; the hidden conversation requires knowledge of previous events to be fully understood. The update also includes new areas, enemies, and a secret boss, but the hidden conversation is the most significant addition for lore enthusiasts. According to Kotaku, the conversation was deliberately placed in a hard-to-find location, rewarding dedicated exploration. Casual players may miss it entirely, but for those who seek it, the payoff is a major narrative revelation that sets up the final chapters.

Common Questions

Where exactly is the hidden conversation located in Deltarune Chapter 3?

It is found in Castle Town, behind a bookshelf in the library that can only be moved after obtaining a specific key from a side quest. Interacting with the revealed wall triggers the dialogue.

Does the hidden conversation change anything about the game’s ending?

No, the conversation does not alter the ending of Chapter 3 or 4. It is purely lore-based and does not affect gameplay or unlock new routes. It only provides context for future chapters.

Is the hidden conversation canon or just a teaser?

Toby Fox has confirmed via his Twitter account that all content in the official updates is canon. The conversation is considered part of the game’s main story, not an Easter egg or non-canon joke.
