Have a Golden Saint Soldier (a male Golden Saint) follow you back to Cyrodiil after completing the quest where you help the Golden Saints retake their stronghold from the Forces of Order. He speaks to you as usual in Shivering Isles when you talk to him, but when you try talking to the Golden Saint Soldier in Cyrodiil, he will say nothing and the subtitle will display "I HAVE NO GREETING". This is probably the placeholder for the greeting that characters give you when you engage them in conversation, which is put in before the greeting is programmed. Note: This only works if you follow the path where you become Duke of Dementia as this quest where you meet the Golden Saint Soldier will not be part of your questline otherwise.
