Hello, This is a very interesting idea. Although I can imagine it would be a little difficult to place/summon a magma river somewhere in Tamriel and leave it as-is. I have found something greener though. The Skyrim Reforestation mod allows you to purchase and learn spells that add trees and foliage to Skyrim. You could completely reforest a wasteland if you would like. http://skyrim.nexusmods.com/mods/35842//? Misplaced objects can be removed through the console command markfordelete, and entering a different area. Perhaps you could contact the mod creator and ask whether or not he/she is able to create a mod with man-made structures. You could also ask whether he or she would be able to share the resource files with you. Best of luck to you! :)
