"What? Is that easy? Wait, isn't this exactly the same as creating a coup?? All they had to do was assemble a group of people go through the fortress and kill the king and queen. What is so different and official about this?"
"It had to be done on an offshore island. The person asking for the position of the King and Queen needs to prepare a lump sum of money that would be used to build the entire defence fortification of the King and Queen desires. All of the expenses had to be paid in full before the Royals could go in and stay with the number of guards they wished to employ. As for the employment of guards, that is under the Royal's decision." General Grieves explained.
"Not only that, the challenger had to start from the sea where they had to go through a sea battle to reach this undisclosed offshore island and later fight their way to reach the King and Queen. Should the challenger die, then that's the end of the duel."
