The Windhelm Butcher shitters!
In his Museum of the Lame and Boring, Calixto Corrium has what we might call a “dummy shitter” that this serial killer wants you to THINK is where he craps. Think again. In the bottom photo, which shows the interior of the hidden room at Hjerim, we see the real deal. Calixto dismembers his victims here, also drinks wine and eats friggen cheese and crackers here, and yes shits here too. Nice chamber pot, you filthy misogynist.
