Spoiler

NOTE: This is my first attempt at making datapacks, be aware there might be problems you may encounter.

Theres something up in the skies....

This datapack adds a whole new dimension, the Alpha Islands!

It consists of 3 new biomes, the Sky Forest, Plains and Desert, each with different looks.

You can get there by getting beyond the buid limit via elytra, launchers... or the new Potion of Flight!

Theres also a new structure located in the Overworld, wonder what it could be...

Sunset over the islands.
