So, I have realized that time is passing WAY too quickly in my fiction to keep everything constantly updated - as I am trying to catch up with actual fiction universe time. So, starting in the next 24 hours, I will be (trying to) abruptly shift my fiction's planets and overview to their position in 50 NE, instead of late 41 NE like I am in now on the history page. I am sorry if this is a bit abrupt, but I need to finish this, and the only way I will ever be done is by updating it every decade instead of trying to every year.
As such, the population figures will be slightly over what the empire actually has (due to being updated with information from a bit over 8 years in the future) starting tomorrow. As for UDB stuff, just ask at any given time and I will give you the current figure.
