absolutely not. If you are using this mod everyone in the multiplayer session will need to have it installed.

is this modless friendly

Land of perception and tragedy

Are you accepting suggestions? I do have some for you ((this may be applied if someone download certain mods that puts new class aspects as well)) how about: land of the flow and music, land of culinary and essence, land of the clockworks and steam, land of the metal and circuit, land of the canyons and fireworks, land of the volcanoes and art, land of the biodiversity and restoration, land of the crystals and energy, land of the waterfalls and color, land of the mountains and wind, land of the sinkholes and creativity, land of the mushrooms and ink, and finally land of the monoliths and wisdom

You're very welcome! Looking at your mod, I see you did a few things differently in the "Land2" folder, yet they work just fine. It means that following the naming patterns already present there doesn't actually matter at all. I will update the guide with this information right away.

Thanks for making the guide! It was extremely helpful.

I make a guide on creating lands and new lands show up in the workshop, just as I had hoped for. Excellent work! :D
