With the SpaceFarer’s Collective, Keres is often referred to simply as “The Refinery.” Multiple facilities exist across the entire moon dedicated solely to the refining of raw materials to turn them into something usable. As a result, Keres is, hands-down, one of the busiest ports in the entire system, with material being dropped off and refined ore between taken elsewhere.
Citizens of Keres have a reputation as dour workaholics who have no time for frivolity or other nonsense like that. It is not entirely unfounded, and rumors persist that the Collective has … altered them for that result.
Travel to and from Keres is very tightly restricted, with no weapons of any sort allowed except by authorized personnel.
