What is The Deltarune Wiki?

Updated

The Deltarune Wiki (deltarune.wiki) is a community-maintained encyclopedia for the game Deltarune, currently holding about 1,058 articles and 5,061 files. It is freely editable by anyone, even without an account. If you want structured reference material on characters, enemies, items, or locations — rather than discussion or news — this is the site's primary purpose.

What the wiki covers

The main page organizes content into several browsable categories:

Category What you'll find
Characters Main characters, Lightners, Darkners, and a full character list
Enemies Basic enemies, bosses, and Shadow Crystal bosses
Items Consumables, weapons, armor, and key items
Locations Hometown, Closet Dark World, Card Kingdom, Cyber World, TV World, Dark Sanctuaries, Flower Kingdom

It also links out to official game links (including where to buy Deltarune) and community links, so it functions partly as a hub as well as a reference.

How it describes the game itself

The wiki frames Deltarune as an official successor to Undertale, set in a parallel world with new characters and music, returning characters, and an upgraded battle system. The premise it gives: join Kris, Susie, and Ralsei on their quest to restore balance between Light and Dark.

On release status, the wiki states the game had a paid release in 2025 and is still in development, with up to seven Chapters listed in the Chapter Select. It notes Chapter 5 has been released, Chapter 6 is planned for 2027, and Chapter 7 has no release date yet. These details change over time, so check the live page for the current state.

Who runs it and how to take part

  • Editing: Anyone can edit, with or without an account. The wiki asks contributors to add only relevant, accurate information and to avoid speculation or false information — and to correct false information when they spot it.
  • Discord: The Undertale/Deltarune Wiki Discord server is where day-to-day operations happen — discussing content, reporting mistakes, suggesting changes, or just talking about the games.
  • Discussions: Uses your wiki account; posts cover important wiki projects you can join.
  • Bluesky: Posts updates and occasional trivia.
  • Languages: The wiki lists 9 languages, including Español, Français, Italiano, 日本語, Polski, Português do Brasil, Русский, Türkçe, and 中文.

When to use it — and when not to

Use it when you need encyclopedic reference on game content: looking up a boss, checking what an item does, or browsing a location's page. It is also the place to go if you want to contribute corrections or new articles.

Be cautious with anything tied to unreleased chapters. The wiki itself warns against speculation, but fan wikis can still accumulate unverified claims around upcoming content. For release timing, treat the wiki's announcements as a starting point and confirm against official channels.
