The whole world is simply a custom superflat preset. It is a superflat "overworld" world in a plains biome, reminiscent of dreamcore landscapes. It generates structures like strongholds, mineshafts, villages, and ruined portals. Ores generate underground along with amethyst clusters. I do not believe there is any deepslate.
This is just a world that I need to upload in order to use in a modpack.
