From The Stargate Omnipedia
An area of land on M4D-058 populated by the Geldarans, who are being instructed how to live their lives by a console on Atlantis. The Geldarans leader's name is Nola.
The land got it's name because Rodney McKay, whilst operating the console on Atlantis, named it for a girl he went out with twice at school.
The Game - Rodney McKay is hailed as "The Oracle" when he arrives in Geldar.
