Salis is a city on an unnamed planetoid inhabited by Acmarans, who call it the "city of perfect peace" (The Law of Volahd, Part 1). It is, however, the location of Cylons experimentation on organic life forms, overseen by Volahd, a Cylon who comports himself as the Acmarans' deity (The Law of Volahd, Part 2).
Salis is the origin for the force field that results in the deaths of Viper Cadets Colin and Lomis (The Law of Volahd, Part 1), which is powered by a cyranite power source that powers the entire city in addition to this force field (The Law of Volahd, Part 2).
Salis is destroyed when Taron discovers that he himself is a cybernetic construct, modified by the Cylons to allow the Cylons to experiment on his people, and throws a Centurion's severed head into the energy column. With the power source disrupted, the force field pulls in Volhad's baseship which collides with Salis (The Law of Volahd, Part 2).
