Thers nothing. no towns no cities not even bannerbank?
If you’re trying to use the /warp command, it won’t work as that command is a server-side plugin. You will have to teleport to the co-ordinates listed in the warp list provided next to the download link.
Make sure you’ve placed the world file in the correct place:
Inside your .minecraft folder you should have a saves folder, inside that is the download and directly inside that is the region directory.
If it goes something like saves/Creative-1.12/Creative/region it won’t work.
