Understand Why Mods Require Citadel

What Citadel Does

Citadel Unofficial Port Mod is a code library—a collection of shared tools and functions that multiple mods can use instead of each including their own copy. This approach:

• Reduces file size and memory usage
• Prevents conflicts when multiple mods need the same features
• Makes updates easier for mod developers
• Keeps your game running smoothly without redundant code

Why You Need It

Mods like Alex's Mobs and related projects are built on top of Citadel's foundation. Without it installed, these mods cannot function—they'll fail to load or crash immediately. Think of Citadel as the engine that powers these mods, running entirely behind the scenes.

You'll never interact with Citadel directly in-game. It has no items, blocks, or commands. Its only job is to exist in your mods folder so that dependent mods can access the code they need to work properly.
