Sulfur Cave Labyrinth
by braytonk4
Sulfur Cave Labyrinth generates a puzzle structure underground, where players decode clues to find the one true path through a maze of dead ends and false vaults.
What it does
The mod is distributed as a Data pack and adds a procedurally generated maze called Sulfur Caves, located mostly underground. A small surface entrance, built from sulfur bricks, holds a hint toward the opening stretch of the correct route. Four large chambers off the entryway supply the clues needed to obtain the Sulfur Key. Players apply what they learn in those chambers to move onward, while many false vaults and other dead ends are placed to mislead them.
The structure fits alongside vanilla world generation. It can be found underground with the locate structure command and the structure's identifier, so players and server owners can reach it without searching by chance. Choosing the wrong vault means losing the single key, so each choice carries weight.
Only the server needs the data pack; players may join without installing anything, and the server is the only side that has to run it. The files target 26.2 – 26.3 and are published for Fabric, Forge, NeoForge and Quilt. The license is All rights reserved, so the mod is not open source.
Key features
Underground puzzle structure
The Sulfur Caves are a primarily underground structure built as a puzzle rather than a fixed dungeon.
Clue-based navigation
Clues gathered in the entrance and the four chambers are used to decode the route through the maze.
False vaults and dead ends
Many vaults and passages lead nowhere, so each choice has to be weighed before a key is taken.
Locate command access
The structure can be found underground with the locate structure command, which helps players and admins reach it.
