I created Empire of Calradia and got the Stop conspiracy quest. If there's no way to finish that quest like it has been said in some posts it shouldn't have been implemented in this state. It keeps failing and restarting again. We need to see an update finishing the main quest, or it should be edited without the interference from the other quest giver for now. I stopped playing that campaign since I saw some posts indicating that when it fails 3 times all factions will declare war on me. I don't know what else it would do. Main quest and Diplomacy should be top priority for future content updates.
