This setting is made to work with the Free System. It is a huge setting, where some 500 worlds are given names, political relationships, and some stats. It gives species sheets for the humanoid species of the SC2 setting: Human, Sastra, SaHu, Vantor, VaHu, Tagris, and HuTa. It also gives the worlds of the Aztec System in detail, to show how you can build up detail from a few stats.
