Abna was a Cali-Katchna native who served as a cleric in the city of Cali-Katchna on Skygowan during the mid-23rd century.

In 2261, Abna escorted Doctor Roger Korby up to their spiritual high chambers for a meeting with High Cleric Zeperez. He informed Korby that Zeperez, a Vezda possessing the reconstituted body of Dana Gamble, was promised to them and would deliver them to their gods. A short time later, Abna had gouged out his eyes in preparation for Vezda possession, and was praying in the temple. (SNW: "New Life and New Civilizations")
