Nadarr
Nadarr is an evil, sadistic and likely insane Dragonborn Wizard who resides in the Demiplane of Excrement.
He is a very powerful magic user with impressive mastery of illusion, telekinesis and demiplane magic. He has created the Demiplane of Excrement as his personal domain, where he built his twisted flying castle, Within the castles, many rooms open to even smaller demiplanes which he uses to entrap and torrment his victims.
Nadarr appears to be able to create Magical Tapestry Portals or at the very least able to connect the demiplanes he creates to the portal networks in order to lure and entrap unsuspecting travelers. He also seems to be capable of temporarily disabling the function of said portals to prevent his victims from escaping.
When travelers enter his demiplane via the tapestry portals he usually presents as a gracious and eager, if a bit pushy host. He invites them to his castle for a grand feast. Unbeknownst to the visitors all food served in the castle is actually feces (either Nadarr's or that of one of his other captives) made to look, smell and taste like actual food via illusion magic.
All Nadarr ever eats is cake.
When he is not tricking his victims into eating his feaces, Nadarr usually forces them to entertain them by performing the inane, awfully immature plays he has written, singing songs he composed and etc.. All the plays and songs are usually about feces or bodily functions and designed to humiliate the performers.
If he is pleased with the performances he rewards his guests by allowing them to retire to their bedrooms. The bedrooms are actually separate demiplanes that Nadarr populates with either real monsters or illusory enemies that his guests need to fight, or run away from. If the guests refuse to perform for him, he locks them in the flooded dungeons underneath the castle where he deprives them of sleep for days either using loud noises or electric shocks.
Actually, scratch all of that. Nadarr does not exist! He is a figment of your imagination.
None of that stuff ever happened!
