Leilana Dee sees herself as the control subject in the science experiment called life. Often labeled as "boring" and "predictable", Leilana Dee keeps her wild and experimental side reserved for pet projects. This boring lifestyle leads to her being considered anti-social and when she does join others, instead of relaxing she prefers to keep quiet and observe.

Every legendary story seems to have at least one charming and optimistic character. If that's the case, then it only makes sense that Leilana Dee has decided to be that person. After all, if everyone is too busy whining and groaning about the negatives, how will anyone ever reach the positive? True, Leilana Dee's constant belief that things will get better can be terribly grating, especially to pessimists or those just level-headed enough to realize when things truly are going downhill, but Leilana Dee's constant positive outlook can serve to sometimes spur others to action when it feels like the world just wants them to lay down and die.

While generally laid back and more than happy to offer a quip of sarcasm, Leilana Dee's entire demeanor changes once combat begins. She becomes focused and quiet, with her smile replaced with a look of grim determination.

Leilana Dee is a lateral thinker, and when she encounters problems or dilemmas, she is very good at improvising and coming up with alternative solutions. This allows Leilana Dee to find ways out of situations others might give up on. While these solutions are often not so obvious to others, Leilana Dee can typically explain and lead others through her plan...as long as they are patient and willing enough to trust her outside thinking.

Leilana Dee doesn't like to kill people; instead she chooses to injure her opponent until that person is unable to fight back or is otherwise incapacitated.

Leilana Dee seems to get her thrills, perhaps sadistic ones at that, from toying with her opponents. Some are content with simply striking down or injuring their opponent, but that is not enough for Leilana Dee. No, she wishes to see her enemy descend into madness or kneel before her as a blathering mess; or even better, as a fresh new servant with a muddled mind. The Puppeteer usually forsakes outright hurting and maiming her opponent and focuses on illusions, mind tricks, and other wicked means of destroying a person.
