Mongol invasion. Population went from 600 -> 0

An invading army came asking for a LOT of gold. I could have gathered it if I sold off a lot of buildings or something I think.

Unfortunately, I didn’t have anything to trade during the 12 months. I built up a small army instead. But the invading army was way too big.
They left only after killing every villager and destroying every building. I don’t think there is anyway to play after that.

Let me guess…vanquisher right?
