Abna was a male Cali-Katchna and cleric in the city of Cali-Katchna in the planet Skygowen. [1]In 2261 Abna took Roger Korby up to the spiritual high chamber, a pyramid type structure that floated above the city, in order to meet with their high cleric Zeperez. Once there Korby realised that Zeperez was, in fact, the Vezda lifeform that had occupied the body of Dana Gamble. Zeperez had promised Alba that he would deliver the Cali-Katchna to their gods. In preparation Abna and many other Cali-Katchna had gouged their eyes out in readiness for being possessed. [1]
