K'Tara is a niece of the head of the noble clan S'Vass, a cadet branch of the ruling M'Vissi clan, in control of one of the 54 Counties of Ferasa. She was given command of the salvaged and rebuilt World Breaker to develop her gravitic weapons tech to its fullest, after she proved its worth with her ground-scale "grav gun." During the Iconian War she served as an exchange officer with the KDF, only returning after the signing of the Treaty of Sauria necessitated a restructuring of the then-small Ferasan fleet. Currently, she and her command are technically on loan to the Klingon Defense Force, despite her independent status under the Ferasan fleet.

For personal defense, in addition to her grav gun, she carries a compressed-tetryon railgun revolver she received as a gift from her uncle, as it is meant to remind others of her noble family. It has also proved effective on the battlefield as well, however, on the rare occasions it was needed.

Zahara is the official head armsman for, and personal bodyguard to, K'tara for the past ten years. When K'tara moved to her new command, Zahara took over as head of security, as she wouldn't trust anyone else with it. She has a strong preference for melee weapons, preferring to beat her opponents up close and personal. She has attracted the attention of quite a few males of several species, but she has repeatedly stated she would only consider someone worthy to be worthy of attention if they can best her in an unarmed wrestling match. In her entire career thus far none have been capable of this, despite it being a weekly thing among the marines to try. At this point, she's honestly not sure what she would do if someone finally did.

Brother and sister, these two have been unofficially nicknamed the "Terror Twins" by the crew of the Worldbreaker, as they are well known for ignoring all ethical and moral considerations in the pursuits of their own scientific interests. That same ruthlessness however is what got them their posts on board the Worldbreaker.

R'Moll is the male sibling of the two, specialized in the biological sciences. While officially the Chief Medical Officer, most would be prefer to be under the care of one of the other medical staff as he tends to be more fascinated by the body's reactions to the wounds than the wounds themselves, not to mention the various experimental remedies he attempts when given the leeway to do so. He is also an excellent xenobiologist, which is the true reason for his posting. While in most cases he gets along with his sister well, to the point they can finish each other's sentences, when it comes to romantic interests they will often end up fighting for the affections of the same lucky(or unlucky) woman.

S'Danza is the female sibling of the pair. Her specialty is temporal mechanics, with a deep understanding nearly on par with K'Tara's understanding of gravitics. Given the close relationships between gravity and time, she was assigned to evaluate K'Tara's research for any temporal applications. When it comes to relationships, she prefers women herself, which often brings her into conflict with her brother over her attraction of the week. So far, most of her romantic interests have not managed to last longer than a Terran month, usually just after her brother has abandoned his own attempts to woo her dating partner.

Ket is a distant cousin of the M'Vissi clan, but so far removed from the succession that you would not know it if not for his clan markings. He is an expert at getting anything, usually through unofficial channels, and as such doubles as the ship's quartermaster. While he considers himself a suave rogue, in truth those he previously courted merely humored him due to his clan name. He is also a master improvisor, though not quite on the level of a Federation engineer. He would likely have had a much more impressive career if not for his mild addiction to Ferasan Nepata leaves, which has been his bane many a time, costing him several prominent positions on other vessels before his transfer to the Worldbreaker. K'Tara is not exactly pleased to have him here either, but admittedly, he is resourceful, and taking him on board earned her a few favors from elsewhere in the family.
