The Kingdom's Character Limit feature limits the number of characters that can be wandering, performing activities or participating in events in the Kingdom. If the limit is exceeded, the Kingdom will still continue to operate normally, except that any new characters will be sent home. Characters that have been sent home cannot level up, participate in any Tower Challenges or battles, and won't be able to complete any story quests or activities that are already in progress. You can return characters to the Kingdom at any time if you are below the limit.
