Has no one considered grand-son? Togo was, after all, already quite old.
However, I must say that I never considered things to go that way. See, I rather suspect that someone at Anet has noticed that MoP and the Guard don't like each other, and that canonically, the final purging of the empire is undertaken by an emperor, not a popular uprising.
Now... I'm rather thinking in the context of... Emperors, ministry leaders that might be the children of a certain family, whose daughter was mentioned to be of great beauty...
I think we'll see another wedding, myself, and the tone for us foreigners will be much darker than for the locals.
Of course, this explains why I don't really think the ministry leaders are related to Kisu.
Although, come to think of it... maybe the ministry leaders ARE royalty themselves and will depose Kisu, with the emperorship transferring to their branch of the family...
Ain't wild guessin' fun?
