The planet Naranjan's primary terrain was spread over many small archipelagos, one of which was the location of the planet's Stargate that had been placed on the planet many millennia ago when the Ancients still roamed the Milky Way galaxy. Whether or not they stayed on the planet remains unknown, but by the time the Tau'ri had constructed Stargate Command there was no evidence left on the planet of any Ancient colonization efforts. Despite this lack of Ancient civilization, Naranjan was home to both sentient and non-sentient species which had psionic abilities. At some point in time Naranjan was also visited by the Asgard, who discovered these naturally psionic species but did not interact with them in any way.
