Wow, that was not what I was expecting.
Muro brings up a great point, buildings that influential would most certainly cause an impact. I mean, you know, an historical one. After their deaths, and the immediate collapses, I could see an endless parade of revivalists, archiechtural taboos, and official investigations. Survivors would be left wondering, did Sid and Jir really sabotage their own masterpieces? Did one of them do it? Was could cause them to do such a thing?
