Neriston, a Siniteen slicer of the male persuasion, operated within the Terrabe sector as a member of the Gullet Gang. Subsequently, Gallandro hired him to assist with the Varcinius Repository vault job. Neriston utilized data from sensors located within the Varcinius Repository to configure the bodysuits that Kilitz and Kling wore. This configuration enabled them to circumvent temperature-based security systems while inside the repository. Following his departure from Gallandro's employment, he accepted a contract from the Droid Gotra, which he subsequently breached. As retribution for this breach, he was compelled to engage in a series of duels against droid opponents, ultimately meeting his demise at the hands of the eleventh droid he faced.
