Yaaarvak has a legendary and virulent need for vengeance. Once crossed, he will make it his life’s work to ensure that whatever slight was received is repaid tenfold. This need for vengeance can be all-consuming, and can often lead to short-sighted decisions.

Yaaarvak is devoutly loyal to his House or Clan and will follow orders unquestionably. He would sacrifice his own life to protect his House or Clan from harm. This attitude, however, often clouds his ability to see things from an arbitrary or objective point of view and he can come off as extremely narrow-minded.

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

Yaaarvak tells it like he sees it, when he thinks it; and he doesn't try to sugar coat what he says.

Through careful study and dedication to isolated martial-combat, Yaaarvak has turned the act of dueling into an art form. A keen eye and attention to detail allows him the ability to learn their opponent's idiosyncrasies while fighting. Yaaarvak then uses his own skills to capitalize on the opponent's weakness. Because of this calculated approach to isolated duels, Yaaarvak has a harder time taking on multiple opponents at once at higher skill levels.

Yaaarvak is utterly devoted to success in combat, no matter the mission, no matter the cost. He has spent his life building himself in the image of war, utilizing a dogmatic regimen that has lead him to a single-minded obsession with military success and requires intense physical and mental training. This training, however, has come at the cost of anything resembling empathy or concern for others - even his superiors and subordinates.
