Warlock – “Cultist” [Campaign 4, Mission 3]

I didn't leave the previous mission until Railag obtained all the Chaos spells of levels 4 and 5. There's a treasure trove of mages and a dragon utopia there. An enhanced Mighty Dragon destroys almost the entire enemy army. However, I haven't progressed very far yet – I've only captured 2 castles and all the mines near the first castle. I captured the second castle on the last day of the second week. Now I'm waiting for the demon. I hope he arrives soon. If there are problems, I'll change my tactics. I'll try to quickly capture both castles and move on.
