Ye'ten (Ail'ka III) is the third planet from the sun of the Ail'ka system, Xi'an Empire (SaoXy'an). Terraformed for the express purpose of agricultural production, Ye’ten is a world in which all available arable land is being used to grow food and other important organic staples, raise livestock, and ferment raw ingredients to supply the rest of the Xi’an Empire. It is estimated that decades of rations are stockpiled there in case of emergency. To reduce the chance of travelers bringing contaminants or invasive species to the planet, the only area open for landing is a sealed and tightly monitored enclosure.
