Sulxiros grew up never knowing his family. He was sold into slavery very young, and was put to work almost immediately. However, due to his age, Sulxiros bounced from owner to owner until he became a teenager. Having to endure horrible treatment during this time in his life, Sulxiros has lingering trust issues while carrying an absolute hatred toward slavers. If confronted with acts of slavery, he will most likely lash out in some way, regardless of it compromises his objective.

While Sulxiros will see a job through to its conclusion and put forward his best effort, it’s still just a job. Sulxiros's true loyalties lie to his friends, and through thick and thin,he will stand by them and die for them if needed. This loyalty is reserved for those who have earned Sulxiros's trust, putting him at odds with other Mercenaries that are only doing a job for the money. This also makes it harder for employers to trust his motives, often times creating extra competition and difficulty finding work. None of it matters to Sulxiros, though, because loyalty to his friends is not something credits can buy.

Sulxiros is not afraid to exploit any advantage or position of power he has when dealing with others, and relies on a combination of fear, intimidation, manipulation and shows of strength to convince others to compromise and lose. Sulxiros can be quite callous in his dealings with others, and never gives up his power. This has earned Sulxiros with the reputation of a “bully” and can often make negotiations difficult before they even begin.

Sulxiros is extremely cocksure and headstrong. Possessing a keen wit and exceptional level of intelligence, Sulxiros will often use his superior intellect to humiliate lesser minds. Basically, he is kind of a jerk, and that can sometimes get Sulxiros in a bit of trouble.

Even the most gifted of weapon masters understands the importance of physical fitness and disciplining the body with through martial arts training. Sulxiros has trained vigorously in unarmed combat by fusing Teräs Käsi and Echani with other unconventional forms. While this martial focus helps bolster his prowess in close-quarters combat, Sulxiros is still limited in scope when facing down a less direct or ranged threat.

Through careful study and dedication to isolated martial-combat, Sulxiros 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. Sulxiros then uses his own skills to capitalize on the opponent's weakness. Because of this calculated approach to isolated duels, Sulxiros has a harder time taking on multiple opponents at once at higher skill levels.
