Th4rn's Kaos
by Th4rn
Th4rn's Kaos is a NeoForge world generation mod for 1.21.1 that adds new mobs, equipment, ores and blocks to an otherwise vanilla world.
What it does
Kaos introduces new entities and structures alongside several ore types, including Purponye Ore in its standard, deepslate, raw and block forms, and Aetherian Purponye Ore. Other blocks include Therirack, a Blue Ghoust Trophy and a Therijuice fluid. The content leans toward chaos: the author describes it as an expansion that shakes up the regular Minecraft world, with mobs and equipment added to the mix.
The mod suits players who like to explore new terrain and look for ores that vanilla generation does not place. It is a server-side only mod, so players can join a server running it without installing anything, and the server owner decides whether the content is available. The mod is not open source; it is released under the Creative Commons Attribution Non Commercial Share Alike 4.0 license, and builds target 1.21.1 only. The author notes that the current upload is an alpha, with a full content list available on the project page.
