The "Frontier" is home to an unusually large number of different kinds of sophonts. Most of these inhabit only a single world or small region of the Frontier, and a few worlds are actually home to a number of races - Volturnus, the most famous example, is home to five or more.
Four races stand apart a having created the multi-species interplanetary civilization known as the "United Planetary Federation". Three others are part of the mysterious "Rim Coalition". A final race, the Sathar, are the implacable enemy of the UPF and the Rim Coalition and are included for the creation of NPC's only. Detailed descriptions of each race are available at the Star Frontiers Wiki; links are in each species description.
