Citadel, Unofficial Port is a community maintained library mod for Minecraft 1.21.1 on NeoForge. It updates the original Citadel code with compatibility fixes for modern APIs, deprecated calls, and the Alex’s Mobs 1.21.1 port. Designed for client and server use, it works quietly in the background rather than adding a new gameplay system.
Its framework supports advanced entity animations, entity properties, and model handling required by compatible mods. On a Minecraft server, it helps dependent content load correctly while keeping the experience lightweight and close to vanilla. This port is not affiliated with the original developers. BoxToPlay makes it easy to include in a modded server setup.
