The End is a barren wasteland, or was, as Alien End completely overhauls the Vanilla End. Giant trees, stalactites under islands, cooler small end islands, and even 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.
New structures will be added in a future update.
