A planet shared by two rival societies, the Kes and the Prytt, whose division blocked its entry into the Federation.
Kesprytt III is home to two distinct societies. The Kes are eager for Federation membership, while the isolationist Prytt reject contact with anyone, and the two peoples distrust each other deeply.
In Attached, an attempt to beam Picard and Crusher to the Kes is intercepted by the Prytt. The two escape with telepathic implants that link their minds, revealing their feelings for each other. Picard concludes that the planet's division means the Kes application cannot be accepted for now.
