The most esteemed familial position a member of a Chiss family could achieve was the rank of blood. Ar'alani, who later became an Admiral, was born as a full-blooded daughter of the Irizi family; however, this changed when she was elevated to the rank of flag officer. Those in the Chiss Defense Force who attained flag rank or higher, beginning with the rank of commodore, forfeited their familial standing.
The attainment of blood rank brought with it significant respect and advantages within Chiss clans. Beyond the advantage of receiving favored handling in family matters, holding blood status improved a Chiss's professional opportunities as a non-military administrator within their family.
