Hallona was a nation on M4D-058. The Hallonans are neighbors with the industrial nation Geldar. They nearly started a war against each other, until they made peace with the help of the Atlantis expedition. Their much revered 'Oracles' were, in fact, Rodney McKay and John Sheppard, who did not realize that their game in Atlantis was being played out in reality elsewhere. (SGA: "The Game")
