The lineage of Kassido stood as one among seventeen noble families establishing themselves within the Senex-Juvex territories, following the enactment of the Ruusan Reformation by the Galactic Republic. Locating their power base in the Juvex sector, House Kassido exerted control over the planets of Kassido and Ossiathora. Through commerce with star systems situated in the D'Aelgoth sector and extending towards the Core Worlds, the Kassido aristocracy amassed considerable wealth. Nevertheless, these interactions with external entities resulted in a diminished reputation for House Kassido among numerous inhabitants of Senex-Juvex. The humanoid Kardurans existed as a dependent species under House Kassido's patronage.
