Hello @Lukas04!
It’s great you’re getting into modding! However…
You should take a look at this thread: One Rule to Ring Them All
We have a rule (it’s the One Rule!) that you should not modify the work of others in the community without their explicit, written permission. So before you put a ton of sweat and effort into a new mod, you should check this. The Canyon Mod – created by @BrunoSupremo falls into this category. (Obviously, it’s fine to create a mod that is based on the work of the Stonehearth dev team.)
Thanks!
