Sera is a naturally trusting person. It doesn't take a lot to gain her confidence; and once someone has it, it takes a great deal to lose it. She thinks the very most of her friends; they are the salt of the earth, diamonds in the desert. The idea of betrayal, dishonesty, or dishonor on their part is unthinkable. This means that she will fight to her last breath for the lives of her companions, for their safety, honor, and revenge against their foes. But, it also means that, in the event that she is stabbed in the back, the betrayal will hurt all the more.

There are stubborn people, pigheaded people, strong willed people.. and then there is Sera Kaern. Once committed to something, whether it be a person, a mission, or an ideal, she will not back down, as long as she is able. Under torture or duress, she will persevere, even when it is foolish, and even when her life is on the line. Pain is temporary, after all, but honor is forever.

Sera Kaern is very cheerful and happy, and always looks on the bright side of life. When chewing on life’s gristle, she doesn't grumble, but gives a whistle. She always hopes for the best, and enjoys laughing, smiling, dancing or singing. This unending optimism often improves the morale and spirit of everyone around her, and Sera Kaern is always quick with a smile or a joke, even when drawing her terminal breath. This same exuberance can also be tiring to more jaded curmudgeons.

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

Sera has always believed that the most important part of a hand to hand engagement is unpredictability; a grandmaster of any art won't remain that way for long if they fall into routine in their fighting. So, training with her brother, she developed her own unique fighting style; an intense combination of K'thri, the traditional zabraki martial art, and Mandalorian core. This kind of fighting strips the ordinarily flashy acrobatics seen in many K'thri forms, and replaces them with the deliberate, brutal aggression favored by the Mandos. The result places great focus on extremely harsh, rapid flurries of blows, meant to overwhelm an opponents defenses, before finishing them with devastating kicks. It is an effective technique; unfortunately, it doesn't leave much room for defense. Constant attack must be maintained for it to work properly.

Born with an intractable will and limitless courage, Sera Kaern will stand in the face of insurmountable odds and never retreat. Despite the fact that such acts of heedless bravery are inspiring and will sometimes result in victories worthy of song, just as often they result in her allies getting wounded or killed.
