Known Legends
by FurPuro
Known Legends is a NeoForge magic mod for 1.21.5 that adds glitch-themed entities, blocks, effects and lasers to the game.
What it does
Known Legends brings a glitch theme into the world. Glitch entities and glitch grass apply a new glitch effect that damages players at times, and glitch blocks can appear underneath a player without warning. Glitch lasers add a vertical beam with particles and a matching effect. The mod also changes some game text, so a player may see messages such as "Something broke..." in the interface.
The content is organized into four phases. Fire and air play a part in some interactions, and the author notes a phase where air is the only element that can cause infection. The mod needs Geckolib and Kotlin for Forge, and it runs on client and server, so both the server and every player need it. Files are published for NeoForge only, for 1.21.5, with 0.14.0 as the latest build from 2025-10-11. The code is open source under the MIT License.
