I loved Cub's Hermitcraft season 8 megabase so much that I decided to mod it into Minecraft. It took some work to get this all working with MCreator, but I'm happy with the result. The Enchanted Desert biome is now able to spawn in-game. I've hidden a couple secrets in it that I did not show in the video, so you'll have to download the mod to find them for yourself. This is only for 1.17 for now until MCreator updates to 1.18.
