"While we are all gathered here today," Therius added before he could leave, he eyed all of the Ministers with a blank look. "I wish to discuss the rights of succession because I know that some of you will be reporting this to my cousin, Prince Yared."
"Your Majesty!" the Ministers blustered and all looked at each other.
"I have found my heir to the throne," Therius stated.
