Guuki (Dagudashaag/1207)
The Guukian Federation is a psioniphilic pocket empire that includes the nine worlds arranged in a triangular cluster between Guuki (1007), Uddiki (1206), and Sirshur (1208). This normally peaceful, early-interstellar pocket empire is being invaded by the Kimalad Empire. Currently lacking the technology to carry the war back to Kimalad, they have been forced to fight in their own space, attempting to repel the invaders.
Marlakasi (Core/1615)
Originally a barren world (and therefore not formally a member of the Imperium), by the year 13 it had been colonized by the deposed government of Shibasiim. At that point, the small population was mostly made up of psionicists, although a few of the loyal nonpsionicists from Shibasiim also migrated here. Naturally, it is very psioniphilic. By the year 15, formal diplomatic relations had been established with Cleon's government, with a clear intent to join the growing empire.
Shig (Massilia/0510)
This high-population world has built its culture around psionics. One of its inland lakes has the curious property of interacting with the psionic powers of those who go beneath its surface. The first time a person with psionic potential immerses himself in it, his powers are unlocked. Additional immersions result in a temporary but substantial increase in the person's psionic level.
Pilgrimages to the lake are required of every citizen upon reaching adulthood. Thereafter, only those chosen by the government are allowed to return. The highest psionic talents are conscripted into government service "for the good of the world." Shig is a member world of the Third Imperium. Its current ruler, Queen Kaliena Wain, is guiding the world to greater integration into the interstellar community while trying to preserve its unique culture.
