About
Castle Shift adds procedurally generated, four-floor castles to Minecraft’s world generation, placing them naturally across a wide range of biomes. Castles include walls, towers, and corridors, with randomized templates for floor sections such as walls, corners, centers, and towers, so their layouts vary from one structure to another. Each castle independently selects materials for its roofs, walls, and stairs: roof options include spruce, dark oak, deepslate bricks, dark prismarine, red nether bricks, and crimson; wall options include stone bricks, deepslate bricks, polished blackstone bricks, sandstone, and end stone bricks; and stair options include bricks, stone bricks, polished granite, deepslate bricks, polished blackstone, polished blackstone bricks, and red nether bricks. Some stone-brick and polished-blackstone-brick walls may weather into cobblestone, andesite, or cracked variants, giving the structures a worn appearance. Datapacks can customize castle placement, including spacing, separation, and biome filters.

Security
No harmful code found
We checked its files and read their code, without running it.
Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.
How we checked
- FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.42 latest files: the newest file for each Minecraft version and loader. The answer above is about the 37 for recent versions. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
- Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.Read without running it
- Author on ModrinthThe disclosure form on Modrinth, where the author declares that the project reads or edits things on your system outside the game. Since 13 Aug 2026, Modrinth's rules require it when this applies.Nothing declared about your system outside the game.
- Looked for, not foundWe looked for these in the file and did not find them.The internet, folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.
Privacy
We found nothing it sends
We read its code without running it: it contacts no web address while you play.
Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.
How we checked
- Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.The code of all 37 files, for recent Minecraft versions. See each file in Releases
- Author on ModrinthThe disclosure form on Modrinth, where the author declares crash reports, usage data and advertisements. Since 13 Aug 2026, Modrinth's rules require it when a project collects data on its users or shows advertisements.Nothing declared about crash reports, usage data or advertisements.
AI
AI was used for its code and text
The author declares AI code and text on Modrinth.
We looked for AI tools in its texts, files and images and found none.
We have not read its code history yet.
No sign of AI in the game
We found no AI service, AI library or AI model file in its code.
Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
How we checked
- Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.Declares AI code, text. No AI features declared.
