Setting information

There's a lot of setting information from a "Pact Worlds" perspective -- specifically a human perspective -- in Chapter 12 of the CRB. Most of it is pretty irrelevant to this setting but feel free to read it.

This page contains italicised text as excerpts from the CRB, the rest is homebrew elaborations for use in this campaign.

Gods & religion

 * There are no "real" gods like in medieval settings or Starfinder core. Worshippers may believe their god speaks to them or answers their prayers but there is no evidence to verify this.
 * Some individuals still profess a religion of some kind, but that god does not make themselves known in any real way (as above). Furthermore, the transition to life in space not only tends to require the shedding of religion in the first place but also soon leads to scriptural nonsense (eg. that the sun god circles Earth means little to worshippers who've never seen their home planet or sun. Similarly, that a god created a planet in a number of days means little to someone who's never experienced a day) which rapidly loses traction as the generations progress.
 * Nonetheless, some religiosity persists but isn't universal to an entire race (and sometimes even crosses between species from different planets).

Magic use

 * Not all races (species) can use magic like in Starfinder core. The appropriate organ/technology/mechanism is required to perform the "magic".
 * There is also considerable debate as to what counts as magic and what is simply not yet explained/understood. Shirren pheromones and Lashunta sensory organs certainly give some humans the feeling that something supernatural is taking place but these aren't shocking abilities within their own communities.

Race
Basically refers to species as the core rules. Each species has races that would've been localised regions on their home planet, but the transition to a space faring society unavoidably increases their ability to/technology for global travel and, as such, in general, little if any racial differences exist within a species.
