Arriving on the galactic stage approximately one thousand years ago, Structs are a race of sentient, self-replicating machines. Represented by the Structs Conglomerate—a loose federation of self-organizing factions—their origins and culture remain relatively unknown to the galaxy at large, with the Conglomerate providing few historical records and rarely permitting visitors to Structs-controlled worlds.

As synthetic intelligences capable of simultaneously piloting any number of distinct hardware platforms, Structs are uniquely suited to the hazardous conditions of Alpha Matter mining. While other species have struggled with clumsy automated outposts, unpredictable rudimentary artificial intelligences, and unreliable remote operations prone to human error, Structs are able to establish efficient and largely risk-free Alpha bases, suffering the lowest recorded failure rate of any Alpha-capable species in known space.

This expertise has led Structs to become essential to galactic mining efforts, with most major species forming political and economic alliances with various factions within the Struct Conglomerate to acquire Alpha Matter. This has occasionally created conflicts within the Conglomerate itself, with factions competing to fulfill the needs of their allies or contracted clients—sometimes leading to raids and open conflict between rival operations.
