Create: Caeruleum
by gotitim
Caeruleum is a NeoForge magic mod that adds a fictional transforming substance, the caeruleum, which grants special magical effects when players consume it or are exposed to it.
What it does
Caeruleum introduces a single fictional substance themed as a drug within the game world, and its effects are the mod's central mechanic. Players can feed the substance to themselves and to other players, and the mod describes its effects as strong, with a simulated dependency that the author says is intentionally heavy. The substance can also be spiked into food, so a player may consume it without knowing. The mod's real-world substances served as reference material for its design, and the author states that they were not used in any way that could be taken as a drug recipe.
Create: Caeruleum can run without the Create mod, which is listed as an optional dependency. Installing Create adds the full feature pack that the author built around the substance. The mod is open source under the GNU Affero General Public License v3.0 only and is published for 1.21.1. The author notes that the code was partly generated with AI and checked by hand, and that the AI usage is disclosed on the project page.

Caeruleum is a simple mod adding a truly magical and transforming substance granting you special effects! Somewhere in the frozen north, where the world is full of snow, there was a civilisation. It was a prosperous, thriving land, but now... it's gone. But... there is one place that survived. Long, long ago it was…
