The Salia system is a star system on the fringe of the massive Covenant Empire. It contains a single Covenant colony world, Joyous Exultation. It is one of the systems under the protection of the Combined Fleet of Righteous Purpose. During the Civil War of the Covenant, the system was a strong point for the Swords of Sanghelios.
A disaster occurred in this system in 2552 when Joyous Exultation and its moon Malhiem, was destroyed when a Grunt called Kwassass on the CSO-class supercarrier Sublime Transcendence inadvertently triggered a NOVA Bomb.
