Xun Rao & Emperors Usoku and Angsiyan
I would assume that resurrection only really works for mortal wounds. It doesn’t stop you from ageing and one would assume that dying of old age/natural causes would be pretty final. I don’t think a person could just be infinitely resurrected beyond normal life expectancy, at least not without it being very noticeable appearance wise.
Usoku took power in 1127 AE. Xun Rao is an adult in 1079 AE. He would be 48 years older – making him a ripe old man even if he was a young adult during Winds of Change. This seems highly unlikely, especially given how Canthan emperor succession appears to work – which is to the closest male kin of age (often a son). To quote An Empire Divided in this:
This means that although the throne has not always passed directly from father to son, it has always gone to one of royal blood—at most, a first cousin (as seen in several well-documented cases).
To claim this person has been in the works for even 200 years longer seems… even more unlikely. Though it wouldn’t be via resurrection, but magical longevity if such were to occur.
Stop treating GW2 as a single story. Each Season and expansion should be their own story.
