Hebridan

Hebridan was a planet in the Milky Way galaxy that had two distinctly different races living in harmony, the Hebridians and the Serrakins. The Serrakins came centuries ago to this planet and helped the Hebridians to get free from Goa'uld control. They also offered technological advancements. It's also known to happen that the two races mix in marriage. In 2006, shortly after the devastation of Dakara, Hebridan was reported conquered by the Ori, and has not been heard from since. . It's probably that, with the use of the Ark of Truth, Hebridan would likely be liberated. (Stargate: The Ark of Truth)

Behind the scenes

 * In "Space Race" when the planet could be seen from space, a piece of land on the right side of the planet looks exactly like the Arabian Peninsular and the Indian Sub-continent on Earth, but upside down.
