I started playing as a Necromancer. At the end of the first week, an Inferno with "Medium" danger emerged from a dungeon in the corner of the map and attacked my castle. After the battle with it, I had 41 skeletons left. Two days passed, and another Necromancer with "High" danger emerged from the same place and gave me a hard time). Was I just unlucky, or is this how it's supposed to be?
