Hrakkour IV is a planet, the fourth planet in the Hrakkour star system. A class M planet, Hrakkour was formerly a holding of the Klingon Empire, in the Klingons' space in the galaxy's Alpha or Beta Quadrants. This planet is home to an advanced lifeform known as Bialbi. Bialbi ordered Kenka to leave the Hrakkour system and never return on pain of death. Bialbi further ordered that no Klingon vessel was to ever return to Hrakkour, however he invited Captain Kirk to return, finding his level of social development pleasing.
