Kruss Gaal served as an operative stationed at Darkside, a repair facility situated within the Cularin asteroid belt. Furthermore, he held membership in The Cell, a criminal organization aiming to overthrow and supplant the local crime lord, Nirama. His position within The Cell was not particularly prominent, nor was the Darkside faction of great importance within The Cell's overall plans.
Following a raid conducted by Nirama's forces in 32 BBY, Gaal was among the few surviving members of the Darkside group. Other survivors included individuals such as Ahlya, Dor Balse, Jarrilyn, Jasper, and Michael. At this juncture, they actively sought to enlist new members, including local Wookiees, Kaarl the Ithorian, and several recent arrivals; however, the Darkside personnel held the local Cell in contempt. Shortly after this recruitment effort, they were apprehended by a team of spies acting on behalf of Nirama.
Within a month, his involvement with The Cell and the resulting capture became widely known.
