One thing that i noticed in oblivion is that prisons were not that important, so i was thinking that in skyrim there should be different. One thing that i would like to see changed is the size of them, I also think that if a persons becomes really dangerous than he should be sent to a prison for the worst criminals, and that prison would be the size of a city with the worst criminals in skyrim or it would be like one of those oblivion forts that go underground, what do you think?
In medieval times prisons weren't used frequently used, it was usually used as a place for criminals to wait until they were executed or tortured to death. Why lock when your criminals when can just kill them?
