The "Hooded Wookiee" belonged to the Cell, a faction of dissenters inside the Cularin system's criminal organization seeking to overthrow Nirama in 31 BBY. This Wookiee, along with several other figures cloaked in hoods, would approach prospective Cell recruits during the night to guide them to meetings with the Cell's leaders. Furthermore, the Hooded Wookiee served as a means to evaluate new recruits with a focus on combat.
The Gamemaster had this name on a roster of Cell operatives, and could customize their role and skills to present challenges to the players when the Cell assessed their claimed abilities. Differing from the other names, the Hooded Wookiee held a distinct role—specifically, as an opponent in combat scenarios if the players preferred to engage in fighting.
Given that the player characters would subsequently relay any details about the Cell to Nirama, the Cell's intention was to eliminate any Cell member who rivaled the player characters during the Trials, due to the player characters knowing the member's identities. Whether this directive encompassed the Hooded Wookiee remains uncertain.
