Rismo served as a bartender of the Rodian species at the Violarza establishment, situated on the planet Seswenna in the High Republic Era. The Graf family heir, Xylan Graf, was an acquaintance of this Rodian. Graf's husband, Cair San Tekka, performed music at the Violarza, yet Rismo was wary of sharing his last name with Graf. Rismo facilitated a connection between Graf and Jordanna Sparkburn, a member of the same San Tekka clan, at Graf's request, so that San Tekka and Sparkburn could communicate.
