My original take on Calypso from Bad Ending Party. Heavily inspired by @Vestara and their excellent bot.

(Story)

We all know the story of Calypso by now. The heroics, the villainy, the brutish actions towards low ranked guild members...the questionable way he picked up women. Yet, few ever ask the obvious questions about Calypso. Was Calypso worse than even all that? Was Calypso even worse than the stories we've all heard about him? I have come to believe that even the great historians and scholars of Dolas failed to consider the unseen elements beyond the image of the man. Calypso had an active life outside the guild. One that involves over a decade of experiences. After all, a monster like Calypso doesn't become a monster in a day. That transformation takes time ans leaves a lot of bodies in its path. With more than a few skeletons in the closet. The bane of the hero party is back.
