Built by those serving Coeus, Saelmgar was a series of complexes spread across mountainous spires. In the Creation War (1486 DE - 8777 DE) this huge area served as an armaments factory in the war to turn back Creation.
In 2660 DE, the Covenant general Takarrûs attacked Saelmgar. A forlorn mission from the start, the death of Takarrûs triggered a great explosion. This opened a rift, taking a section of Saelmgar and all those inside, to the faraway world of Bal-Kriav. On this mortal world, this alien landscape came to be known as Mughakh-Gol.
Built up over thousands of years in the Creation War, Saelmgar is today a dangerous and lawless area dotted with nearly a hundred ruins.
