she is probably the darkest character on this list and has the saddest ending.  

after all the elements were restored, the world could function well without the power of the elements. because of this they took a hiatus from the elements and continued with their previous lives. during this time, Tylynn was offered to become Queen of Night. she spent weeks thinking about it. once she accepted the offer she began to change. sh became cold and distant. she no longer wanted to be with her old friends. moreover she had frequent disputes with Yin, who just became King of the Day. when she asked President HyunSuk about her problem he explained how that the night was considered evil. all of it’s past rulers, including her father, were evil. her original personality would soon be totally consumed by the need for more power. days passed and everyday she seemed even more distant. when she became completely evil, she had a dark blue hair, and crystal blue eyes with a diamond shaped pupil. her eyes screamed evil and soon everyone in the company was afraid of her. however, their feelings disappeared when Yin confronted her.Tylynn began to feel a surge of jealousy in her body as she watched Yin rule the day. she became upset when the people slept through her night.countless times has she tried to take Yin outside during her night to show him all the great things she does. however she gets her request denied every time. from what started out from silent crying, it went up to the plotting of her eternal night. she took on her real name Qian and started her plan. she devoured the fear that emitted from the people the second she walked by. she enjoyed the reign she had going. however,  she never thought that Yin would come and ruin it all. ok i don't want to ruin everything because Qian does get a story. it will most likely be the sequel to this one. but her story will be explained a whole lot better in that story because this is just the elements of harmony. Tylynn's transformation into queen won't be explained as through here but it will be the story I plan on making.
