I had an idea of a fanfic where Yui was saved when Aang went kaiju-mode without a problem and the FN fleet is destroyed. However, Azula shows up while everybody is exhausted and bluffs her way in to capturing the NWT and the Gaang flees. Azula scrambles to establish control of the city and rescue survivors and send for reinforcements.
According to NWT law, the only way that a treaty as important as surrender can be ratified is through marriage, so Azula and Yue are wed. Azula rules benevolently to repair the the city because an uprising would be deadly, with Yue as source of local information, intermediary and moderator and they grow closer.
