Ruyn Myr has a sick sense of humor, viewing the world through dark colored glass. She has a biting sense of black humor, often laughing at things that most people would find reprehensible or down right soul crushing. As a result, those that are not used to her brand of humor often find Ruyn Myr downright unbearable or overly morbid. At the same time, her cynicism can be useful for seeing through the optimistic altruism of those she encounters.

Ruyn Myr doesn't like to work in groups or teams and feels most comfortable on her own. Ruyn Myr sticks to herself, sets her own pace, and doesn't share feelings or emotions with others. While the Lone Wolf can get things done quietly and efficiently, she tends to be emotionally cut off and has problems relating to her comrades.

Ruyn Myr has a tendency to be secretive and keeps to herself, relying on deception to conceal her motives and intentions. She is a schemer, and plots and plans against others carefully. When dealing with a confrontation, she will try and bluff her way out of trouble, or overcome obstacles with deliberate, covert actions.

Ruyn Myr possesses a cold and completely uncaring demeanour. This will manifest itself in the fact that when push comes to shove, Ruyn Myr will just as soon leave a struggling ally behind rather than put themselves in danger. While this may ensure her survival, it often leaves her as an outcast amongst her peers.

Ruyn Myr 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 Ruyn Myr. 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.

Ruyn Myr vastly prefers ranged combat, taking every opportunity to use skills and Force Powers to disengage from melee and instead fight at range, so much so that she has become competent at staying out of melee in the first place.
