Sanctuary – “Life in death and death in life” [Campaign 4 – Mission 4]

gutlaf, I completed it in about 6 hours on normal difficulty, so I don't think it will take long. Demons attacked me, or rather, always the same one, with a small army. People started attacking after I captured their cities, but it wasn't difficult to repel them if I developed the cities correctly and quickly. By the way, I captured the castles of the Duchy as quickly as possible and didn't let them recapture any cities, which allowed my army to grow very quickly... ;)
