Ergol

Ergol is a star system near Tzenkethi space.

In 2383, the Federation began to colonize planets in the Ergol system for inhabitants of worlds that had been attacked by the Borg during the 2381 invasion. The efforts antagonized the Tzenkethi Autarch Korzenten, who  did not want a Federation world so close to the Tzenkethi Coalition. Tzenkethi harriers later began attacking shipping to the Ergol system.
