Incendium (mod)

Incendium is a Minecraft datapack created by Starmute. It is designed to overhaul the Nether using only Vanilla blocks. It adds 8 new biomes and 9 new structures which contain custom mobs, items, and advancements. It is entirely server-side.

Incendium is packaged as a Minecraft mod for Forge and Fabric for ease of installation.

Compatibility
Incendium overrides the dimensions for the Nether, so modded biomes will not generate there. This is caused by BiomeSource being overwritten. This can be bypassed by deleting the  file in Incendium's source code.

Amplified Nether
Amplified Nether is incompatible with Incendium.

Infernal Expansion
Infernal Expansion is broken in Incendium, see § Compatibility.
