In the Fars Empire, government departments paid salaries every Monday, thus in the Fars Empire, Monday was affectionately called — Empire Payday.
Most lords in the Fars Empire collected taxes on Tuesday, thus Tuesday was affectionately called — Lords' Tax Day.
The person responsible for the infamous Baron Fabolais Tax Day Massacre was Charles, who was refurbishing the Knighthood at Machu Picchu.
As he led an entire Knighthood into Machu Picchu, a thought immediately transmitted through his diary, telling him that he could undergo the third "Maze-ification."
Charles originally had no desire to go to the frontline and fight to the death for an Imperial Duke he didn't even know, so he settled down to refurbish in Machu Picchu, as the Westwind Knights needed training and motivational speeches anyway.
