About this Mod

The End is a barren wasteland, or was, as Alien End completely overhauls the Vanilla End. Giant trees, mysterious tendrils under islands, vibrant small end islands, and geodes add much more vibrancy to the end and make it more exciting to explore. Alien End also adds naturally spawning Endermites to the End.

Alien End only changes the vanilla biomes making it compatible with many mods and other data packs.
