Many were injured, but none died in her kingdom. She made damn sure her people were protected. If something happened to them, she would never forgive herself.
Though she killed the enemies, Jessica still managed to escape but she gave her a present. Lea wanted to kill her with her hands but there were more pressing matters than running after that bitch. She had to pass judgement for those who sinned and apologise to her people, for she tricked them.
She didn't want them to think she wanted to control them, on the contrary, she wanted to get along with them just fine.
Many things have happened and this was one of those days they had to experience horror and appreciate life more. People always want more than they can chew, but Lea was to make sure this will come to an end. Her people and her kingdom will not be controlled by schemers and shrews anymore.
