I killed Cicero and now I feel guilty. I'm an assassin, yes, but he was a dark brother after all. I hear he's also good at sneaking and I like having followers with me, but other followers aren't as good at sneaking and get me detected. Now his corpse lies in the Dawnstar Sanctuary and I have to stare at him. It's driving me crazy.
Is there a way to bring him back permanently and not as a zombie for 60 sec? Are there any in-game means? Or a console command, perhaps?
