Life-Service Bond (Omólogo ypiresías zoís, خدمات باند زندگی), a condition of enduring contractual obligation between patron and patronee, estimated at a nominal sum reckoned as the life-debt (chréos zoís, بدهی زندگی) of the supplicant, redeemed in increments by the value of services rendered to the bondholder. Originates in Neo-Babkhan and Raspurid customary practice, subsequently popularised in the Imperial State of Constancia during the reconstruction period after the Second Euran War.
Following Raspurid practice, the recipient of a life-service bond is known as a Kul in recognition of the honour thereby bestowed through meritorious service to a higher purpose. A Kul generally enjoys a position of greater privilege and protection than is afforded to the bandaka class of unfree persons, typically Androphagi or latterly Iterans, who mostly labour as helots and serfs on public farms.
The life-bond was a practice usually encountered only in Raspurid and rural portions of Constancia, as the urban population, comprising mostly of refugees from Vey and the Euranikon province, enjoys - almost without exception - the continuation of previously held citizenship rights. It is not entirely unheard of however for citizens, particularly those oppressed by economic hardship in the refugee camps and resettlement cities, to voluntarily seek out a patron - whether state, corporate, or private, as a means of alleviating adverse circumstances.
This however changed during 1698 AN with the conquest of northern and central Eura by Constancia, in concert with Nouvelle Alexandrie. In Greater Molivadia and Shahzamin the entire population was reduced to servile status and made subject to the life-service bond, their fate to be auctioned in the burgeoning markets of Nivardom and deported to the vast new manufacturing complexes with which Constancia proposed to solidify its leadership of central, eastern, and southern Eura.
In 1708 AN all Constancian subjects under the terms of a life-service bond were made available for service with the Grand Commissariat of Eura and Corum and placed under the discipline of the General Inspectorate of the same at the the direction of the Committee of Euran Salvation. This change saw 370,000 kuls drafted by the Grand Commissariat for construction duty on the Trans-Euran Railway for a three year period of indenture (I.1709 AN–XV.1711 AN).
