Good idea, but I suspect it conflicts with lore about Magika somewhere along the line. I'm not sure though. By no means am I a TES lore buff.
*shrugs* just a theory. me and my nerd friends discuss things like this on occasion, and that's what we came up with. that and the fact that when their doing their final touchups and asking "have we forgotten anything?", generally the first thing that comes to mind isn't "we forgot to research an era specific waste disposal solution to include for additional realism"
where does a bear go?... in the woods? we can only assume so, and maybe the people follow the wildlife example. let nature take care of nature.
sorry if i'm rambling, it's tomorrow and time for me to sleep lol
