V0.2.0 has been released to Patreon!


FREE PREVIEW SERVER: flubberschnub.my.pebble.host
Join the above server ip in 1.20.1 to preview the datapack and experience how it all works!

This datapack is a project I have been working for about a month as I post this. The goal of the datapack is simple: add the dimension behind the Deep Dark portal. What does that mean? Well, for Nyctocosm, that means:

- A mysterious, frightening new dimension with environmental mechanics and completely custom world generation
- Many custom biomes, each with unique atmospheres and properties
- Custom structures with mysterious secrets to find
- Custom mobs, with unique drops, mechanics, and animations
- Custom bosses: 3 main bosses, one secret Final Boss
- A custom soundtrack, composed by yours truly and others
- New items; weapons, gadgets, and more!
- A custom magic system that is robust, flexible, and dynamic
- Lore
- Much more!

Join the Discord to chat and see updates as they come out!

Installation Tip: When installing into an already created world, make sure to completely exit and re-enter the world instead of just running reload, since the dimension needs to generate!

The new boss Cataclysmic Emissary is an angel of pure destruction and chaos. She has four phases, all distinct from one another, requiring different fighting styles to succeed. The dynamic custom soundtrack will add fuel to your fire as you dodge and strike. With almost all her attacks dealing enough damage to instantly kill an armorless player, this fight will take all you have.

To fight the Cataclysmic Emissary, explore the Nyctocosm and find an Infernal Chasms biome. In this biome, perform the spell of Incurrence (the same one used for the other two bosses). Once the spell transmutates, the battle will begin.

If you are able to defeat the Emissary, you may be rewarded with the new weapon: Semblance of Doom.

Good luck, and enjoy!


Artifacts can be found in the new Crypt structures in chests.

To use the new artifacts, they simply have to be in your inventory. Their effects are passive/triggered, which means you won't have to actively use the artifact items for them to work.

Artifacts look like this:

The Nyctocosm Minecraft Data Pack

Each artifact has a magic type, a perk, and sometimes a detriment. Here, the Tablet of Transposition allows the user's spell plane to move with them. However, that means the spell plane will need to be recast every once in a while.

Some artifacts may look like this:

This means the artifact works with the new Semiaxiomatic Hypertrace system.


Hypertraces are a new system that works hand-in-hand with spellcasting. A hypertrace is an orb of magic that appears, by default, in two situations: when the user casts a spell, and when the user deals magic damage. By default, there is a 15% chance of a hypertrace being generated whenever these two events occur.

Hypertraces look like this:

A user can interact in three main ways with hypertraces:
"Destroy": punch the hypertrace. Sneak+punch will destroy all of the user's currently active hypertraces.

"Pick Up": right click the hypertrace, which will add to the user's "Hypertrace Charge" amount. Sneak+right click will pick up all of the user's currently active hypertraces.

"Near": be within 6 blocks of a hypertrace.

These actions can only be done with hypertraces that were generated by the user.

The user may store up to 5 hypertrace charges at a time, but this number can be increased to a maximum of 15.

The three actions one can perform with a hypertrace don't do anything by default. However, that is where the artifacts come in. An artifact such as the Blade of Extraction shown above will modify the events that occur upon interacting with a hypertrace. The Blade of Extraction means that any hypertrace that the user destroys will spawn a soul, which can then be used to charge soul bottles and Planar Coils. This means that a player can do a lot of cool things using artifacts and make very powerful magic builds.


The new Crypt structure is version one of a very exciting "dungeon" type structure. They spawn naturally in the Nyctocosm's Night Wastes underground at a level of 0. They are marked by Stonehenge-like structures on the surface above them.

However, the Stonehenge structures will not necessarily be directly above the Crypt, so you will have to do some exploring to find it.

Crypts have their own music as well as many different rooms, loot, traps, and lore. They are the only survival method to get artifacts currently. There are even some secrets hidden in the depths of the Crypt, so explore them to your heart's content!
