Lets just say you enter a town and begin summoning zombies or skeletons in front of the townsfolk. They are all uneasy seeing the undead after seeing the extent of what has happened in Cyrodiil. The guards approach. "Im afraid I'm going to have to ask you to stop that. With the current events taking place, the townsfolk are a little on edge."
So do you think if civilians and guardsmen witness you raising the dead through conjuration, will they consider it a crime against nature?
I for one would feel it to be a lore accurate response by the inhabitants considering the events that have taken place.
Summoning other creatures with conjuration should be fine, but raising the undead...!? What do you think?
