Shadows Attacked
The young master of the Thalassa family. He is neither from the main family line, nor was he the heir for his branch family line.
He is just one of the many offspring and he happened to be born to a relatively powerful man. He knew that he couldn't do shit in his family's fight for power, so he decided to take the easy way out. He picked a remote city, at the very edge of his family's influence and became its city lord.
This city doesn't have much significance for the Thalassa family.
They occupied it just because they could. The tax that comes from them, the resources they could gain from it, none of these factors are special compared to other cities. It is manifestation of mediocrity.
He picked that place and used his father's authority to make some sick changes.
The old staff was fired or transferred.
New staff was assigned and all of them were women. He just enjoyed his life in debauchery and wanted to do that until the end of his life.
