So I've been around a lot of quest givers recently and I realized that almost none of them have any indication that they are in fact quest givers. So I'm actually asking for everyone to actually mark them as best as they can using whatever means they have so newcomers don't accidently cut them or break them in any way.
Use runestones, place signboards or anything other mean of marking them so no one goes on and remove them.
This has caused a few tensions between people of the same area and simply marking them would help a lot of people to NOT kill the quest givers. Everyone wants to use magic after all!
