The four orders of inheritors[1] refers to the major races that occupy the Wheel. They were created from the Flames of Creation, mostly by the gods, entire races crafted to inherit their creation. The 4 divisions are Sustainers, Protectors, Perceivers, and Destroyers, with each having a role and function in the universe. They are more commonly known as Servants, Angels, Humans, and Devils.


Long ago, the gods established the red city of Throne and populated it with four groups of people. Each was designed with a unique purpose in mind, and as their numbers grew, their lineage would create the foundations for the multiverse, which was henceforth called the Wheel.[2]

The history of these people is a turbulent one, and some people were affected more heavily by the carnage of the Universal War. For example, the angels experienced a massive cultural schism after the destruction of the Concordance.[3]


The Sustainers, or Servants, were created first. They have cool white souls and are the children of the god UN. They include spirits and servants and were made to build, but not perceive the universe. They were created from the Cool White Flame by the god Koss.[4] They do not die of old age. Examples of sustainers include Musko Reeve and Mammon.


The Protectors, more commonly known as Angels, were constructed to protect the universe from the rebellious sustainers by Koss. Their souls are a cold white flame, and the Law was "beaten into them".[4] After Throne was established, the angels served as the attendants of the gods, but the city became corrupted and the gods eventually died out while the angels were left undisturbed.

When Zoss breached the firmament, he slew the original Prime Angels and inherited Throne, creating a new order ruled by the demiurges and ushering in a golden age. It was at this time that the demiurges forged armored bodies of ash for the angels and invited them to take up their role as protectors of the Red City once again. But the peace was not to last. As Throne grew corrupted a Universal War erupted, splintering and demoralizing the order of the Concordant Knights. After the war a number of angels found a new path which led them to become Thorn Knights. Other angels gave up the law completely and became Petal Knights. The angels who remained true to their nature are Root Knights, and created a new order of peacekeepers now known as the Concordant Harmonies.

Examples of protectors include 2 Michael, 23 Liminal Blossom Punctures the Heart of the Unrepentant, Deliciously, and 82 White Chain Born in Emptiness Returns to Subdue Evil.


Perceivers, Humans, are the third order of inheritors. All perceivers have souls of warm black flame, and were created by Aesma. Through her ignorance, she created the humans as mortals, possessing the Gift of Death which bestows their lives with more meaning than those of the gods.[4] Examples of Percievers include Mathangi ten Meti and Allison.


The final order of inheritors, Destroyers, are Devils. Their souls are the hot black flame. They are descendants of YIS, and were not created by any god - humans shaped the flame into the masked humanoids Creation knows as devils. [4] Zoss, the Conquering King, bound many devils into their forms, as did the other demiurges. Examples of Destroyers include Ciocie Cioelle and Himself.

Canon Conflict[]

The first description of the four types of Inheritor gave different names, flames, and creators to the four. 'People', depicted as human (specifically, Allison), were said to be 'black daughters of YIS', and 'Aeons', depicted as armored angels, 'white sons of UN'. Devils, though, were said to be 'white daughters of YIS', rather than the hot black flame mentioned later, and 'Servants and spirits' were said to be 'black sons of UN'.[1] YIS is the incarnation of the hot black flame, and UN the incarnation of the cold white flame[5], so this was a different order - from coldest to hottest, it would be Aeon, Servant/Spirit, Devil, Person, rather than the later ordering of Angel, Servant, Human, Devil. Koss and Aesma were not mentioned, nor were Zoss or the rest of humanity's role in creating devils mentioned. This is probably superseded lore, as devils are very consistently mentioned as being a hot black flame in the comic itself and the quotations beneath it[6], but this is not certain; many contradictions are considered simultaneously true, so it may be true both that devils are hot black flames and that they are white daughters of the black goddess YIS.
