The Kezt were a race that existed thousands of years ago. The Kezt were one of the strongest civilizations active near Rigel. After 700 BCE (that is, 800 years after 1508 BCE, reference stardate −35/0811), the Kezt joined the Nine Worlds Confederation, a significantly powerful alliance with eight of the strongest neighboring civilizations. Along with the rest of the Nine Worlds, the Kezt were signatories to the Treaty of Kammzdast, which governed the use of Orion slaves.
