Personality
Lorcan views the world with a cinical approach not believing anyone or anything is good. It doesn't mean that he can't be cheerful or happy, but it means that he views things in a negative light until someone or something proves him wrong. He is quick tempered and with his past experiences it can put him on the defensive. He's also protective of the ones he cares for though and that proves benefitial to anyone he develops some affection to.
Background
Born into a space colony of more rugged living on the outer fringes of Humanity's reach, Lorcan grew up among spacers, working to further his education. Feeling that he was not skilled enough to serve in a technical position, such as an engineer, or a skilled position, such as a helmsman position, he pursued training in security when he entered the GEAS Space Academy. And he did a damn good job of it. From there he went on five voyages between the ages of 20 and 30, but on his last venture, his ship was boarded by pirates, his cruiser eventually losing its systems and the ship taken over, he was taken prisoner, tortured for a while, and then finally had his arm and left eye removed before he was retrieved by GEAS forces. Only then did he take some time off. He got some new cybernetics and a bit of therapy, but GEAS hated to see such a skilled officer go to waste, and so, after getting him back to some sort of stability, they placed him on another ship as a security officer, where he could embark on a new voyage.
