Elemental Wraith

The Elemental Wraiths, also known as the Firstborn and simply the Wraiths, were the first lifeforms to arise on Argent D'Nur.

Biology
The Elemental Wraiths are large beings, standing at almost three times the height of a Human. While they bear a semi-humanoid torso and head, they have tentacles in place of legs, similar to Maykrs, and bat-like wings in place of arms, with each wing having its patagium held between three crab-like limbs that connect to their upper torso, in a similar position as humanoid arms. They are known to have an endoskeleton, and their heads, while appearing somewhat human-like, only have a large mouth as a visible feature, in addition to ram-like horns on their heads, giving them an overall demonic appearance. Elemental Wraiths are able to fly, and generate supplies of energy referred to as Wraith Essence or Wraith Energy, better known as Sentinel Energy, which can be used for seemingly endless purposes, such as a power source for various forms of technology. This energy can be siphoned out of them and combined with Hell Essence to create Argent Energy. Most notably, Elemental Wraiths are capable of creating a "Wraithcall," an ability described as magic, which is able to either spawn or evolve lifeforms into complex organisms, described to be aggressive behemoths, eventually spawning a hostile planetary biosphere. However, the Wraithcall is also capable of eventually giving birth to smaller, less aggressive, and potentially sapient species, such as the Argenta and other animals that the Argenta domesticated, along with a hospitable biosphere. However, the Wraithcall's prolonged use threatened to drive weak-minded Argenta mad the longer they listened to it. The Wraithcall was only said to be used once over a given period of time, and it is possible that the Elemental Wraiths are only capable of using it once. Due to only three Elemental Wraiths known to be in existence, it is highly unlikely that they have any method of reproduction, and appear to be immortal. They also appear to have an ability to go dormant for extended periods of time, while still generating more Sentinel Energy, and could survive being fused to the Well of Hell Essence for eons with their chests mutilated to expose a spherical energy ball within their bodies, despite being in constant torment. Their level of intelligence and sapience is unknown, although it is known that the Wraiths gifted abilities such as magic to the Argenta and relied on them for protection.

History
The Elemental Wraiths were formed in what was known as the Womb of the World, released from within Argent D'Nur when it was pierced by the Cosmic Spear. The Wraiths flew over the surface of Argent D'Nur, emitting their Wraithcall, which caused other forms of life to spring forth from the ground. These lifeforms, known as Ancestrals, were hostile behemoths who waged wars against each other, ravaging the surface. Eventually, the Argenta came to be, and were gifted with magic from the Wraiths, using it to fight back and drive out the Ancestrals. As thanks for their gifts, the Night Sentinels were formed to protect the Wraiths, empowered by their energy, with the people worshipping the Wraiths as gods, forming the Deag Priests to be their prophets. Their Wraithcall continued for some time, combined with times of strife due to earthquakes and attacks from barbaric tribes. The Wraiths eventually appeared to go dormant, ceasing their Wraithcall and being held within a Sentinel facility. During the Time of Grief, the Argenta were contacted by the Maykrs, who helped them once again become prosperous. As a result, the Argenta shifted their worship to the Maykrs, with the Deags being reorganized to be the prophets of the Maykrs, although the Wraiths remained guarded. As the war between the Night Sentinels and demons raged on, the Wraiths continued to supply energy that powered Sentinel weaponry, which was soon discovered to be able to create Argent Energy. In secret, some of their energy was siphoned away by the Maykrs to create Argent Energy. Near the end of the war, when the Maykr's deal with Hell was revealed, the Night Sentinels shifted their worship back to the Wraiths. At the time, the Wraiths were being guarded by an Argenta known as Valen, whose son had fallen in battle against the demons. Valen was getting visions of his son's soul in torment, and out of desperation, made a deal with Deag Grav, a corrupted Deag Priest, to resurrect his son. To fulfill his end of the deal, he gave access to the Wraiths to Deag Grav, who kidnapped the Wraiths and took them into Hell, fusing them to the Well of Hell Essence, where their bodies were mutilated to have their energy constantly drained and fed into the Well to produce Argent Energy, leaving the Wraiths in eternal torment. Valen's son was then resurrected as a Titan known as Icon of Sin, and Valen, now known as The Betrayer, exiled himself into Hell as Argent D'Nur fell. The Wraiths remained in Hell for eons, until the Doom Slayer came across them in the 22nd Century. They were being guarded by hordes of demons, but the Slayer tore his way through them and freed the Wraiths with a Crucible that he recovered, ending the Well's production of Argent Energy. While the Wraiths were described as being freed, their bodies remained, described as being put to rest, meaning that only the spirits of the Wraiths were now free. For this reason, it is very likely that the Wraiths are extinct, although it could be possible that they live on in other ways, or can somehow regain their corporeal bodies. Even if this is the case, they were not seen again by the Doom Slayer.
