"Really, helots of this farm, this takeover will WORK. Once we have killed Eurid himself, his men will surrender easily without a leader to guide them in battle. And we will enslave them all, and they will do our bidding!"

"Uh, if we did that, wouldn't Sparta come and kill us all?"

And it is true. Your campaign is ruined, and you remain a slave forever.
