The full project, made over 4 months in survival on a small modded multiplayer server. The first idea was to use ores in buildings, in a coherent manner. Every addition to the project has been linked to the ensemble in order to result in one large complex.
The project was built on minecraft 1.16.5. While there was already plenty to do with the available blocks at this point, a lot of blocks in the 1.17 version could have been used and made the project quite different (notably deep slate, amethysts, raw ore blocks).

This has been made using mods. To open the map correctly, the following modpack is required : Béryval pack (1.3)

The download includes a minecraft map to unzip and put in your saves folder.
