Because of this the sisters began a plan to take the thrown either through blood or by blood. The plain went well having the kings bastard child taken away and groomed to kill and replace a his farther who had to other heir to contest the claim. Once an army of men and allied beings had been gathered they marched on the castle and the knights of the realm only to find they here betrayed. The plan went flawlessly the king slain with Clarent the ceremonial blade and with his death the thrown won however due to the meddling their other sister who stood with the white council, not only was the king killed but his son and mother too.
