View source for Yii'ua

'''Yii'ua'''{{SClang|lang=xian|kyexiin=9yii2ua|srx=Yii'ua|srx-meaning=}} are the primarily social, economic, and political structures of the [[Xi'an]], based around genetic lineage. The term is variously described as Line, Lineage, House or Great House, with 'House' being the most common when discussing history and economics. They fulfil the role of both state and corporation within the Xi'an Empire, with each receiving a chartered monopoly from the Imperial House.<ref>{{Cite RSI|url=https://robertsspaceindustries.com/galactapedia/article/box9JmxvWL-xian-house|text=Galactapedia: Xi'an House (Yii'ua)|accessdate=2021-04-28}}</ref>

Careful tracking of one's Yii'ua is mandatory on official public documents, private contracts, etc. in the [[Xi'an Empire]], because the lines are everything to the Xi'an. It's rude to dwell on genetic provenance in polite society. These matrilineal dynasties exist as great Houses, both metaphorically and physically as they grow into great estates and form mega-corporations when they prosper.<ref>{{Cite RSI|url=media/unzs4pdgg5wtir/source/Xian-Language-Overview-31-10-2947_corrected_x5.pdf|text=An Overview of Xi'an Language for Diplomats}}</ref>

Each Yii'ua is presided over by a 'Council of Three' {{SClang|current=Xi'an|meaning=advice group|kyexiin=kyo9lyon|srx=kyoLyon}}, composed of three elders of the House. All aspects of the governance of a House are overseen by its Council, such as the expenditure of fiscal assets, the distribution of food and clothing, and the arrangement of breeding partners to continue the family Line, among others.<ref>{{Cite RSI|url=https://robertsspaceindustries.com/galactapedia/article/Rw1DPO8v8q-council-of-three|text=Galactapedia: Council of Three|accessdate=2021-04-28}}</ref>

The Imperial House {{SClang|current=|kyexiin=9yii2ua9tao3|srx=Yii’uaTao”}} occupies a special position, as it controls the [[Xi'an Service]], the Bureaucracy that oversees the empire and contains the [[Xi'an Defense Forces|Xi'an military]]. All citizens of the [[Xi'an Empire]] are required to carry out a 30 Xi'an year (38.4 SEY) period of service between the ages of 40 and 70. During this time, they officially join the Imperial House and take on the name of the Emperor as their own. Some elect to remain a member of the Service beyond their mandatory period, or return in later life, becoming the officer class of the service.

The Imperial House is also governed by a Council of Three advisors, but these are forbidden from being of the Emperor's own House. Instead, the three advisors to the Imperial House are drawn from high-ranking members of the military, civil bureaucracy, and the practitioners of [[Li’Tova]].
