Septimus Signus’ Outpost shitter!
Septimus Signus, whacky devotee of Hermaeus Mora, lives in a frozen berth just north of the College of Winterhold. Here he has minimal creature comforts, such as an enormous Dwemer puzzle cube, to keep him company. As an old codger, Septimus isn’t going outside to poop in the snow. It’s a constant blizzard out there! So he has this bucket. I believe it’s upside-down as a tribute to how cwazy Septimus has gotten over the decades. I imagine him putting the ewer on top and saying, “Lovely!” Anyway I’d probably store it upside-down too. In that miniature cavern, it may help stifle the stink.
