When we had no ritual currently in place, but one was being cast, the "Ritual Status" tab said something to the effect of:
"There is currently no ritual covering your land and none currently started. Your monarch/steward can begin the casting of a ritual by going to the 'start ritual' tab."
This is paraphrased, I don't have the actual text saved and it's archived in slack, but it was very noticeable, and was confirmed by others in the KD.
