On the very first

'End Turn' of the most recent SP game I played, I was shocked to start reading this "Unexpected Event in Sauromatia" message:

"... decided to aid an old wise man whose daughter was held captive by your blood mages. The young girl and a couple of other blood slaves were liberated in a daring attack on your dungeon."
