Born of the Terrian and Human breed, Karsa is widely seen as a outcast and a mistake. He was the first experiment in sexual reproduction the Terrians attempted. Although he remained very powerful, as they had hoped, he was too emotional. He did not take on a personality in the first day as all the other Terrians had. He was moody and didn't accept all commands without question, something all other Terrians did. He was different. Other then the Ruler, he was the only 'different' one in the whole race. Although he had his short comings, the Ruler took a personal liking to him. He took him under his wing as he trained him to join the Guards. It look years longer then the rest for him to learn but the Ruler taught him regardless, he saw potential. At the Age of seventeen he was admitted into the guard, hoping to prove himself and reignite interest in breeding with other races.

Karsa has dark brown hair and eyes. He looks almost exactly like a human, only differing in that he is slightly more muscular then the average human of his age, He varies between a clean shave and a thin beard. He would usually wear civilian clothing but in times of war he would wear that of a Terrian soldier. He is kind and shy but at times he is very outgoing, speaking to strangers and hitting on women just for the hell of it. He usually feels as if he is less worthy then the Terrians, he could barley handle having to take years of slumber int he core, he couldn't just turn off his mind like the other. The thing that he is most self conscious about is that he has not been with a woman yet, the Ruler constantly pokes fun at him for it. Although very normal for a Terrian not to have sex at all, he was part human meaning it was a little more than expected.
