Their identities are not fixed and are based on species of origin.
Summary
A Lord Ravager is an Emanator who oversees many divisions in the Antimatter Legion, and is selected by the Ruin Author, Nanook.
Despite the countless worlds, civilizations, and lives that Nanook has annihilated, THEY still leave a pathway open to delay the doomsday of some powerful individuals who willingly obey THEIR will or step gleefully onto the Path of Destruction. Endowed with the powers of Destruction, these creatures are twisted into dreadful Lord Ravagers.
Rumor has it that Nanook has seven Overlords, each representing one of the seven extremes of Destruction. But so far, we have yet to find comprehensive data on these seven Overlords.
Both the Alliance's observational records and the IPC's intelligence networks have obtained only slivers of useful information on these entities. After all, there are no remnants by definition wherever Destruction goes, and that includes information. We do not even know the names of at least four of the Overlords, and can only discern their existence by their varied tendencies regarding Destruction.
Observational Records
[Zephyro]
With a terrifying reputation as a one-man army, Zephyro is the Overlord most passionate about violent destruction. Zephyro is obsessed with the raw power and beauty observed in the explosive moment of utter destruction.
In Year 6804 of the Star Calendar, he ignited the sun of planet New Bethlehem, scorching its planetary surface with huge amounts of radiation and instantly turning it into glass. In Year 7143 of the Star Calendar, he stirred up a huge cyclone, smashing the ecosystem on planet Aedirn into smithereens; In Year 7658 of the Star Calendar, he drilled straight through the Moonshield's outer planetary crust, launching an attack on the planetary core that crushed the entire world... These acts of Destruction neatly encapsulate his extreme passion for doomsday scenarios.
Potential threat to the Alliance: Very high.
[Celenova]
Celenova is the front-line general for the Ruin Author.
Though none can comprehend the logic behind Nanook's actions, Celenova is indeed the general THEY most frequently deployed. Her troops spread throughout the cosmos, weaving a network of destruction between the stars through their marches and raids. The Yaoqing, the Zhuming, and the Fanghu ships all have records of fighting against Celenova's Legion minions. Celenova is also the only Emanator of Destruction to ever board a Xianzhou ship. Records from the History of the Xianzhou have her requesting a ceasefire with the Xianzhou Zhuming around Year 5700 of the Star Calendar, requesting the ship to cease fighting her and change course in assisting her to attack the home world of the wingweavers.
Potential threat to the Alliance: Very high.
[Irontomb]
Irontomb's is most adept at attacking technologically advanced worlds.
All survivors, without exception, recount that they witnessed "the fall of wisdom." In a flash, inorganic AI legions are paralyzed or turn against their mates, outer space defense arrays begin targeting the home planet, flying vehicles scatter at random like flies, unable to target the enemy... Irontomb's forte is attacking civilized worlds confident in their technology. Recently, the Xianzhou Yuque has produced intelligence about Irontomb overcoming the Baranza Forge. We must guard against his attack as soon as we can.
Potential threat to the Alliance: Very high.
[???]
This Overlord's name has not been clearly identified, but they have left behind observational records.
Stargazers of the Yuque once produced 152 consecutive years' worth of observational records about the dead planet Syracuse-III. The Legion's front lines crept forward very slowly in this world. It built up an advantage, exerted pressure, and chipped away at any resistance. Then, just like observing an ant colony, they watched as the civilization experienced a slow structural collapse. Similar phenomena also occurred during the deaths of Red Babel, the Ogul ring, and other worlds. Speculation rose that behind the scenes lay an Overlord with the calm, self-sufficient temperament of a chess grandmaster, pulling the strings of strife as war developed.
Potential threat to the Alliance: Very high.
[???]
This Overlord's name has not been identified, but they have left behind observational records.
Based on IPC records, at least 122 planets were plunged into chaos of unknown origin over the past 300 years before their ultimate demise at the hands of the Antimatter Legion. IPC investigators initially leaned toward these being isolated events, but all disaster assessment reports attributed these events to a single cause: "spiritual" disintegration — The internal conflict of belief systems, the crumbling of pillars of faith, the collapse of trust within civilizations, and the complete abandonment of all hope. The Yuque's Divination Commission believes that behind this series of events lurked an invisible Lord Ravager.
Potential threat to the Alliance: Unknown.
[???]
This Overlord's name has not been identified, but they have left behind observational records.
The Intelligentsia Guild has provided us with a light comparison map of the star zone around the Yvanna chain. One-third of its stars have been extinguished by some unknown force in the past 300 years. It would have been impossible for such phenomenon to occur naturally. The Antimatter Legion roams freely across these worlds that are shrouded in darkness, raining down destruction from within this eternal night. Survivors from the Yvanna system term this one "The Sun Devourer."
Potential threat to the Alliance: Unknown.
[???]
This Overlord's name has not been identified, but they have left behind observational records.
Ecologists from the Luofu's Realm-Keeping Commission once researched a strange world that had been completely converted into antimatter. All objects on that world hurtle toward their matter counterparts, releasing a destructive dazzle upon impact. Antimatter Legion creations have always had distorted, twisted appearances. When destroyed, many instantly implode with an intense backfire, dragging their enemy along with them to their destruction. Perhaps this strange characteristic is derived from this unnamed Overlord?
Potential threat to the Alliance: Unknown.

"The Cloud Knights have been created following the Reignbow's edict to fight against Abominations, but we have fought so many battles against the Antimatter Legion since the Alliance's foundation. The Cloud Knights will inexorably come up against minions of the Ruin Author in the foreseeable future, so adequate preparations should be made soon."
