Real World References
Kona is a type of expensive premium coffee from Hawaii.
Kona also means Capital in Hawaiian, but no indication has been made that Kona was the Jitterati capital. Indeed, its sacking seems to indicate it was not. Perhaps it had once been the capital but the seat of power was moved elsewhere.
