IMPORTANT: THIS IS NOT A FREE DOWNLOAD. If you want to experience just a few parts of it you can download the continents of Demaria and Grullhold for free, but keep in mind that not all resources and items will be available, and the world will be less improved. This map should include every resource available in Minecraft up to 1.19, as well as a couple of structures I added as part of my own Creative project. However, because it is significantly bigger, it's available for $8 USD on my Patreon.
Do not claim ownership for this map, and don't use it on public servers. If you make any content with this world in it, please add the link to this page in the description and be sure to mention me.

Anyway, here's a couple sets of coordinates for the major biomes. Enjoy!
