2. Can the Aedric spirits come to Nirn? I had always heard they couldn't manifest themselves on Nirn but then I found these pageshttp://www.uesp.net/wiki/Morrowind:Ama_Nin http://www.uesp.net/wiki/Morrowind:Jon_Hawker
They also crafted the armor and weapons for Pelinal Whitestrake. I know they can't come and go as they please but I'm just a little confused as to when the can come to Nirn, if they can come to Nirn, and when they do are they limited in some way? You know can they only do certain things? If someone could explain this to me I would appreciate it.
3. This question kinda ties into the first. The other worlds that encompass Mundus, do we know anything about them? Do Mortals live there or is it only the spirits? I ask because we've heard a lot about Nirn, Oblivion, and Aetherius, but I haven't heard a word about these worlds and there properties.
