Everline Structures Incorporated is a Humans manufacturer of Housing Exchange (HEX) stations, affordable housing with commercial spaces that are built into hollowed-out asteroids. Although the company offers an extended contract to perform maintenance on their products for ten Standard Earth Years, most businesses and individuals that purchase HEXes opt out of the extra cost and abandon the stations when they become too expensive to repair. Stations that have been discarded by their owners are common throughout the United Empire of Earth (UEE), especially in areas once used for mining purposes. Abandoned HEX stations are often repurposed as by squatters housing or utilized as bases for those who wish to conduct business outside of United Empire of Earth (UEE) law.
