ŗaushau

A ŗaushau /ˈraʊʃaʊ/, or pedigree, is used by Kaushan men with high rank to prove their qualification for the rank.
The official storehouse of all ŗaushaush for everyone in the Eastern Principalities is in the Dīkoyai i Toshauvi (Office of Records, Dītoshauvi commonly) located in the administrative district of Īyonī. A father can bring his son within a year of birth to to have the son's formal ŗaushau drawn up and filed. If someone needs their ŗaushau for some purpose (to take a position in a Kaulīy's court, for instance), they must go to the Dītoshauvi and have a certified copy made, called an īkodi. The certified copy has the official seal of the Dīkoyai i Toshauvi and the signatures of the copyist and the official validating the copy.
It is possible to have a ŗaushau written for girls, as well, but they only trace the male lineage. Their usefulness is questionable, however, as few Kaushan recognize them. More importantly, women are not often allowed in the positions that would normally require ŗaushau.
Having a ŗaushau proving a person's relationship with a famous or powerful person (the original kaulīyash of the principalities are best) can gain one credit and privilege within the major cities of the Principalities. This is done by presenting an īkodi to the party granting credit. For this reason, criminal organizations often have a specialist in counterfeiting īkodi. On rare occasions, a counterfeit ŗaushau has been placed within the Dītoshauvi.
