The Klaha (also known as Denebians) were a sentient species from Deneb V. They are known to themselves as the Klaha, but gained the common designation of "Denebian" because they were the first race from the Deneb Kaitos system encountered by Earth. (TOS novel: My Enemy, My Ally) In the 2260s, the Denebians still practiced the death penalty for a multitude of crimes, including fraud. The condemned would either be electrocuted, gassed, phasered, or hung. In 2267, Harry Mudd was sentenced to death on Deneb, but managed to escape before his sentence could be carried out. (TOS episode: "I, Mudd")
