In the long history, there were various Royal Houses or Imperial Dynasties that were overthrown or replaced by another House (Usually due to marriable ties). Some survived to this day, or some like the Chinese Dynasties has descendants with the Imperial Surname.
However, there were those who eventually died out soon afterward, only surviving through matrilineally or in Cadet Branches. Some royal houses to this day are descended from these former houses, just not carrying the name.
So, given all these options, if you were able to save one, and only one royal house from going extinct, and not being replaced by another through a specific POD (Whether it be an alternate birth or etc) which one?
