The Titan Covenant, also known as the Covenant, the Apex Covenant, the Leviathan's Holy Alliance and the Holy Covenant of Titan, was a theocratic interstellar religious-military alliance that encompassed every species within the western half of the former Terminus Systems; this area was known as Covenant space, and represented one of the three major alliances in the galaxy following the aftermath of the Post-Apocalyptic War, alongside the Galactic Dominion and the Sanctum. The alliance's roots began as far back as before the Border War, just after the end of the Reaper War. Before its official formation, it was limited to the worship of Apexism, with Ocrolya Khabcass as its prophet, with followers in the hundreds. It rose to prominence following the collapse of the Batarian Hegemony, with the new Titan Hegemony forming alongside the Tilthan Connection, with the Yahg Principality joining it later on, and the vorcha and Illium being annexed even further on. The Covenant formed an alliance with the Omega Republic against the New Council and Galactic Dominion, which was maintained when hostilities began in 2205 CE.

After the war, the Covenant remained in a deadlock with the Dominion for decades, although both sides knew war would properly resume eventually. The Covenant's ultimate goal was to dominate the entire galaxy to make way for the Leviathans return to galactic supremacy, and to bring about the renewed imperium. It was believed this "holy war" was to begin in 2253 CE when the Dominion fell into civil war, but the Dominion's deployment of the Citadel-Ark ended any hope of this, with Titan and the entire Covenant leadership being destroyed. The Covenant collapsed in short order, with only a few sects putting up resistance in the years following. The Leviathans would be quarantined to their homeworld by the UGR in 2255 CE, ending any further hopes of a Leviathan resurgence in the Milky Way galaxy.
