Now, first of all, I have not played the Jade Regent AP, and do not know if there is something relevant in there.
But yes, as the situation is Minkai is described as flammable, perhaps even skirting civil war, how do you think the clergy of Shizuru is situated in this political environment.
Worshipers of Shizuru (and most minkaians, I guess) consider the Imperial family direct descendants of the goddess herself, and the concept of honorably serving your liege figures into the religion rather heavily. But with there being such internal strife inside the imperial family, do you think the clergy is divided on the topic of placing the rightful ruler in house arrest and replacing him with a regent?
It should also be considered that followers of Shizuru generally seek out peaceful approaches. Even if there would be political divisions inside the clergy, I think it's safe to say they'd still want to stand united against the warmongering by General Susumu's followers, which definitely has to be happening in times like these...
I only know a scrap of the Dragon Empires lore, but this stood out as an interesting corundum.
There is a great deal relevant there from the Jade Regent AP.
Like, the AP pretty much answers your questions.
The Five Imperial Families are not the goddess's descendants, but they were handpicked by her to rule the land, and they're supposed to rotate which of the five families is in control.
Things have... gone wrong. Right now the clergy of Shizuru are just trying to weather it while they figure out what the hell happened, for the Emperor is missing and the Regent that now rules is a pretty nasty sort, and is actively hostile to Shizuru's faith (generally in the form of levying crushingly high taxes on all of the temples).
Thanks for the answer - if it turns out that no one in my group is planning on running that AP, then I’ll definitely just get it for the lore!
