Do we know what the four alien races are yet? Kasatha and what else?
Eoxians, Mi-Go, Neh-Thalggu, and Vercites. There's Kasatha in the module, but Kasatha tech isn't a topic of discussion in the alien tech article (probably because the ones brought over to Golarion were brought over from a point when their homeworld's tech levels were lower than Golarion's current tech level).
The Eoxians, interestingly (and appropriately) have a form of necromantic magitech; their sample item requires both magical and technological components and counts as both magic and tech (having both a magic aura and tech-like charge-use).
