Alpha Proxima III

Alpha Proxima III or Proxtrey is a Class M planet in the Alpha Proxima star system. Its inhabitants are divided into two cultures, the Lucrs and Sofs, who engaged each other in a devastating exchange of nuclear weapons in a major war around 1168. This conflict killed three-quarters of the planet's population and rendered the southern continent uninhabitable.

The Lucrs and Sofs differed in their approach to the role of the individual in society. The Lucrs were a fiercely individualistic society, believing that the man who made the most of his abilities was a god. In contrast, the Sofs were a communitarian culture that valued the community over the individual. The two groups also used different mathematical practices that had religious significance, with the Lucrs employing a numerology based on units of three making up sets of 99 and the Sofs using base four units making up sets of 100.

Prior to the war, the inhabitants of Proxtrey had space-faring capabilities which the Lucrs used to estabish an extra-planetary missile base on the asteroid Scythe, a former moon of Proxtrey. In the aftermath of the conflict, the survivors worshiped Scythe as a war god.

In 2268, the USS Enterprise (NCC-1701) traveled to Proxtrey to investigate Scythe's unusual activity.
