Levannan was a planet in the Pegasus galaxy which has a Stargate, the planet is one of the worlds Satedans have settled on after the destruction of their civilisation on Sateda. At the Stargate, there is a sentry and an inn. Levanna's capital sits near the Stargate.
In 1998 it settled a few Satedans after Sateda fell to the Wraith; the King of Levanna let them stay and become a part of his guard. But then came the revolution and the King was executed. The Levannans are a peaceful people who trade with other worlds, among them the Athosians. In 2009 the First Atlantis Reconnaissance Team came to Levanna to warn the inhabitants of Death's plan to cull and attack the planet; much like Manaria. Armed Forces of the Genii, Satedan and Tau'ri managed to prevent the Wraith from culling the planet. Levanna has at least two moons, one larger than the other. (SGA: "Legacy: Homecoming")
