Prefecture AT.3 (AT.3) was established in 2082 c.e. at Canyon Base 01 in Arabia Terra, installing a local government and building on the earlier settlement. Our mission is to create a decentralized representative republic on the surface of Mars, a testament to the creativity, intelligence, and will of the human race.

AT.3 elects, by popular vote, a Potentate who is selected to assume all diplomatic and sovereign responsibilities. The Prefecture is then broken up into ten semi-autonomous districts managed by locally elected District Executives. These executives manage the local bureaucracies and become eligible to serve as district elders upon retirement. Elders assume responsibilities of culture and society and form a quasi-aristocracy. These two groups are members of the bicameral advisory assembly whose secondary role, is to advise the Potentate on matters of State.

Our main export is fiber reinforced Martian cement, which is produced in the industrial zones at either end of AT.3. Production is primarily automated with oversight by local technicians. Our agricultural production is managed in a similar fashion. Most citizens engage themselves in research, studies, or various entrepreneurial opportunities presented on Mars.

The main building types are: government HQ, research facilities, community centers and family buildings. The former is the seat of government and incorporates a transportation hub in its base as well as a meeting hall for the airing of grievances. The research facilities are grouped in two complexes; one focuses on the physical sciences and material concerns, while the other studies the humanities and their application to planetary development. Community centers are built throughout the districts and house various programs for everyday life. The majority of buildings are owned by individuals and families. These structures serve as housing and business centers for the multitude of citizen interests.
