Planet in a distant galaxy, inhabited by the descendants of the Alterans. Celestis is the location of Ver Eger, a village populated by humans who worship the Ori. It may also be the location of the village of Ver Isca.

The Plains of Celestis is the location of the city of Celestis, home of the Doci and the Flames of Enlightenment where the Ori reside. The Alterans also originated from this world prior to their emigration to the Milky Way, with the Ori designating their home in the mountains near the Plains of Celestis as "Ortus Malum" – the "birthplace of evil."
