Zora

Zora used to be a nomadic traveler when she was younger and had been all around Sornieth. For many years, she traveled to see many places and many creatures. She had seen so much, that she was deemed to know everything.
Because of this, she was given the title "Omniscient Zora". Many people would come to her asking for advice and answers to their curious questions. She would always be able to answer them confidently and correctly. She simply just knew everything.
While nearing the end of her traveling days, she visited the capital of the White Purity which was located in the Sunbeam Ruins at the time. She had gone through the area many times seeing the empire grow drastically. She had just wanted to visit the place one last time before she went off to settle down for good.
Lemarque, the emperor at the time, had personally come to visit her during her break and offered her to stay in the kingdom with him. She would be well cared for and would act as his advisor. Her wisdom would be well used for the better of the empire.
Zora was hesitant at first because she knew of their nature. The White Purity, although their military had weakened, was still a militaristic empire. She didn't want her knowledge to be used for violence. She didn't want any involvement like that.
However, Lemarque assured her that he wouldn't use her for any military reason. Her purpose would be to assist with actually running and take care of the kingdom. She would give him advice on how to deal with internal affairs or arising conflicts that she may have seen happen in the past.
Still a bit reluctant, she agreed simply for the fact that she knew she needed to settle somewhere. After all, living in a kingdom would be much better than living alone in the wild. Not to mention that knows for a fact that it's better to be a friend of the White Purity than an enemy.
That's how she got to where she is now. She is still working as the emperor's advisor giving advice on how to take care and run the kingdom. Although, currently, she is more focused on teaching Alfred how to eventually run the throne since he is to be the next emperor.
