Alpha Sector

The Alpha Sector is the guarded central sector of Zile City, where the city's creators work in secrecy. Its facilities include the Gravity Core and Central Tower, major structures at the center of the city.

Access and surroundings

Alpha is largely unknown to inhabitants outside it. During the Mastermind Crisis, closed gates and damaged infrastructure make access difficult. Limited knowledge of what lies inside is a separate obstacle from the physical barriers.

Below the sector, unfinished industrial corridors and bridges cross deep lunar lava tubes. These underground spaces contrast with the visible dome and districts above.

Sector and class

Alpha names both a sector and a robot class. Being present in the sector does not establish an individual's classification.

The sector's complete map, dimensions, ordinary civic life, and normal access rules remain unspecified. Its damaged condition during Roger's journey does not provide a complete account of how it ordinarily functions.
