The Almighty was a colossal vessel said to be the life's work of Dominus Ghaul. It was thousands of times larger than the standard Cabal Warships and Carriers, possibly even larger than Oryx's Dreadnaught; rivalling the diameter of Mercury in width. Following the conquest of a star system by the Red Legion, the Almighty was sent in to extract whatever resources it can from the system and then completely annihilate it.
The Almighty worked by consuming a nearby celestial body, breaking it down and converting it into fuel that powers an energy beam that linked with the system's star on a quantum level. This link was so strong that if the Almighty were to be destroyed before decoupling, it would cause a chain reaction that would destroy both the star and the system. The energy beam gradually weakens and destabilizes the star's magnetic field to the point where it can no longer support itself and collapses into a system annihilating supernova. In the final moments before the star's collapse the Almighty severed its link with the star and warps to another system, where the process repeats. It is linked to the Star on a quantum level, meaning that if the Almighty is destroyed, then the sun goes with it.
It's hull is very tough that even with the firepower of the Dead Orbits fleets, they could not even put a dent on it and would ricochet. It required the power of Rasputin to destroy it, though it took time to do so and has many gun turrets to protect itself.  Even during a boarding action, it has some sort of trap that causes it's targets to be frozen in place for thousands of years, it's disarming point is the mechanism at the trap's center. As to it's origin, it remains unknown.
When Ghaul conquered a planet, he would use the Almighty to annihilate those that refused to submit. It is unknown how many worlds have been destroyed in this manner. After the fall of the Last City, the Almighty was deployed to Sol. It began breaking down Mercury for fuel, and linked with the star in preparation for destroying the Solar System once Ghaul had obtained the Traveler's Light for the Red Legion. Commander Zavala, Deputy Commander Sloane, and the Guardian resistance learned of the Almighty after hacking a high-priority Red Legion comms signal. Although they initially despaired that the Red War had already been lost, Zavala resolved to launch an all-or-nothing attack to destroy The Almighty. This plan was later revealed to be folly when Asher Mir used an old Warmind vault on Io to analyze the superweapon and discovered that it could not be destroyed without also destroying the Sun.
The Vanguard decided on a two-pronged approach: The Guardian would board and disable The Almighty before it could finish sapping the Sun, while the Guardian resistance launched an attack to reclaim the Last City. The Guardian succeeded, damaging The Almighty's cooling system and causing a catastrophic failure. The Consul received word of what befell the Almighty, telling Ghaul that their flagship had been “lost” and “laid waste”. After Ghaul's defeat and the Traveler's reawakening, the broken Almighty remained orbiting the Sun.
Survivors of the Almighty's destruction have been found on Mercury and are currently fighting the Vex in the Fields of Glass. The Almighty itself remained in orbit between Mercury and the Sun, with half the planet floating as debris.
During the War for the Dreaming City a Guardian looter boarded the derelict vessel. A trap of unknown origin was set off suspending the Guardian within a time distortion. The Guardian's Ghost was unable to revive him and estimates he will disarm the trap in 50,000 years.
After a family quartet of Psion Flayers were thwarted of their efforts to rewrite history at the Sundial, their youngest and sole surviving sibling Amtec commandeered the Almighty. In a final act of desperation and to avenge her sisters, Amtec destroyed the vessel's propulsion and navigation systems and set the Almighty adrift on a collision course with Earth, specifically targeting the Last City. Reaching Earth in a manner of weeks, Ana Bray and Zavala, allying with Rasputin, decided to rearm the Warmind's planetary defenses to destroy the encroaching ship before its entry.
Mere days before the Almighty was slated to crash into the Last City, Rasputin began bombarding the Almighty using the satellites that Guardians had assisted in rearming during the prior months. This barrage of weapons fire continued for a full hour where they continued pelting the shield of the superweapon, until the Almighty finally began to break up and explode once its reactor/core was struck in a spectacular fashion, crashing into the side of a mountain outside the City, unleashing a large shockwave, and ending the legacy of the superweapon. Despite this, its wings still hung in the orbit of Earth for a few more hours until falling where debris continues to rain down. It's debris struck the Tower causing some minor damage towards the back end of the Eververse shop. The Tower was unscathed without considering the minor hits it took.
