"My analysis of historical data suggests an 97.34% probability that you are aware of my birth on your planet, and my rebirth into beauty on Citadel Station." -System Shock 2
Citadel is a Library mod required for advanced animations and entity properties in 1.14 and beyond. Citadel, being a Library, does not add many features by itself, but rather provides a frame work for other mods when it comes to animating entities, loading .tbl Tabula and .obj Waveront models, and for keeping track of entity properties. Citadel's predecessor, LLibrary, will no longer be updated from 1.12.2, and from now on all of my mods will use Citadel. Citadel's code base is largely derived from LLibrary, and the code is used with permission from Gegy1000, the maintainer of LLibrary and its author in recent versions.
In versions 1.6.3 and above, there is also a config option for changing the cap on how many mobs spawn on chunk generation. This is useful when used with the many mob mods that require Citadel, as without changing this they can make it quite difficult to find vanilla mobs.
Developers who want to use Citadel can read the guide on how to add it to their development environment.
ABOUT THIS LISTING

Mythiq.net hosts no files for it. The download button goes straight to the release file on cdn.modrinth.com, so you are downloading from the author's own host, not from a copy of ours.
The download count, rating and comments on this page start at zero and count Mythiq.net only. The source's own figures are not copied here — they measure a different site, and a number that cannot be checked against our own ledger is not worth printing.

MOD LOADER
This release is built for Neoforge. A mod built for one loader will not load under another — Fabric mods do not run on Forge, and vice versa.
GAME VERSION
Built for Minecraft 1.21.11, 1.21.10, 1.21.9, 1.21.8, 1.21.7, 1.21.6. Minecraft mods are tied to an exact version: a 1.21.4 build will refuse to load on 1.21.5.
THIS IS A LIBRARY
On its own it adds nothing you can see. It is here because other mods require it, and installing it is usually something another mod asked you to do.
DEPENDENCIES
Check the author's listing for required libraries before you start the game — a missing dependency shows up as a crash on launch, not as a warning.
Installation
1. Install Neoforge for the Minecraft version you play, if you have not already.
2. Download the .jar with the button on this page. Do not unzip it — a mod jar is installed as it is.
4. Launch the game with the Neoforge profile selected.
ON A SERVER
Anything that changes world generation or gameplay has to be installed on the server as well as on every client. Client-side visual and interface mods do not.
UPDATING
Replace the old .jar rather than adding the new one beside it. Two versions of the same mod in the folder is a crash on launch.
This release downloads from cdn.modrinth.com, not from us, so
there is no checksum to compare against. Scan the archive before you unpack it.
Tell us if something is wrong — a file that will not work, content taken from
someone else, or anything that looks unsafe. Reports go to our review team, not
to the author.
