I'm currently working on the newest version of my released mod http://skyrim.nexusmods.com/mods/30734, which converts the vanilla swamp into more of a misty marsh/moor which is described in books and descriptions of the land. My goal is to make it seem more like the Dead Marshes and the Barrow Downs from Lord of the Rings. As part of this, I'm working on a version with Draugr that spawn at night and wander the swamps. My problem is that I can't figure out an easy way of doing this that doesn't break immersion by just having random creatures pop out of thin air when the sun goes down. So my question to you is, how can I do this? I'd like to have the Draugr appear after the sun goes down, wander around the swamp during the night and then return to their lairs to hide from the sunlight during the day. Anyone have any ideas on how to accomplish this?
