lMPORTANT: This datapack is an extension for another datapack, Calamity Mod: Astral Infection... recreated in minecraft (Click Here). This datapack also requires a resourcepack which is included in the .zip file you will download.
So, "Calamity Mod: Astral Infection... recreated in minecraft" is a datapack which is, well, a recreation attempt of the Astral Infection from a well-known Terraria mod known as "Calamity". It adds an entirely new post-Nether mini-biome, the datapack's namesake. It also adds two new bosses, Astrum Deus and Astrum Aureus. Basically, both bosses as well as the Astral Infection will receive background music with this addon datapack installed.
