Argent D'Nur

Argent D'Nur is the homeworld of Sentinel people and the Night Sentinels. The realm has since been conquered by Hell.

History
It is said that the planet of Argent D'Nur was impaled by a giant 'cosmic spear' of stone and metal in times primordeal, most likely a form of interstellar spaceship operated by an ancient alien race called Wraiths. The Wraiths are said by Sentinel legends to have given rise to the other lifeforms on the planet, and were revered as gods. It is possible the Wraiths deliberately bio-engineered the planet and introduced life there, overseeing their progress. The Wraiths also supposedly gifted the Sentinels with a form of energy somewhat reminiscent of Hell energy, referred to by the Argentians as 'magick'. Seeing the great potential in Argent D'Nur, the maykr race came and gifted the Argentians with various technological benefits in return of their servitude. Unfortunately, the Sentinel people were eventually deceived by the maykr, following an invasion from hell, with the maykr ultimately siding with the demons in order to harvest the Argentians in the process of generating argent energy. This caused a massive Civil War to erupt between the Loyalists Night Sentinels and the Order of the Deag who followed the Khan Maykr.

Eventually, the Khan Maykr enlisted the help of the Dark Lord to unleash the Hell Legion on Argent D'Nur. With the empowerment of the Wraiths, Loyalist Night Sentinels managed to fend off the Hell Force and almost defeated them. To ensure Hell's victory, Deag Grav tricked commander Valen into betraying his own people with the promise of reviving his deceased son. As the result of this treachery, Argent D'Nur fell to Hell, leaving the Doom Slayer, the former general of the Night Sentinels to lead his crusade against Hell for eons.

Environment
In Doom Eternal, the non-consumed side of Argent D'Nur appears to be a rocky terrestrial planet with a climate similar to that of Earth. The locations visited in-game show a dramatic, craggy landscape with numerous mountains and rocky formations. The environment is dominated by conifer trees, grasses and mosses but any fauna appears to be abscent, possibly due to the demonic invasion. It is said that Argent D'Nur has been split, with one side consumed by the demons - most likely the side seen in Doom (2016). The other side is said to be under control by Deag Grav who resides in the capital where he hosts demonic gladitorial fights. This appears to be one of few places in Argent D'Nur where Night Sentinels still live, proving that their race is not entirely extinct, if still heavily subjugated by the forces of Hell and the Khan Maykr.

Technology
Having given highly advanced technology by the maykr race and managing to merge technology and magic (or more precisely, Wraith energy) together, Argent D'Nur possesses technology generally more advanced than most Earth-based tech. It appears however that the Argentian civilsation has stagnated, and the introduction of argent energy to Earth has lead to the development of many new technologies reminiscent of that used by the Night Sentinels. The introduction of argent energy further enhanced Sentinel society, and is likely the source of much of their technological progress.

The Argentians also operated large mech-suits several hundred meters in height, primarily as a means to battle the enromous titans. This was something that was later done also by the forces of Earth, most notably the ARC. It is possible Samuel Hayden and the UAC had observed and reverse-engineered Sentinel technology in order to accomplish this.

Argent D'Nur
''While some intelligence has been directly retrieved from Argent D'Nur, most of the details we have regarding this location have been extrapolated from decoded tablets and scriptures. Limited data from the remote collection and information decryption of the Corrax tablets suggest that this area is the corrupted ruins of a "lost realm" - a world that has been entirely conquered and absorbed into the Hell dimension. The battle that was fought to claim this area was of great significance, as the spread of Hell's dominion accelerated quickly upon the absorption of the region.''

The Hell energy that emanates from this region passes through a dimensional tear, and appears on Mars at the Argent Fracture.

From the Corrax tablets:

"All falls before the command of Hell, for our power is absolute, our march to victory inevitable. Before our armies, even the Elemental Wraiths of Argent D'Nur were subjugated. In that great victory the Night Sentinels, the protectors of the Wraiths, were betrayed by one of their own, and the wretches wept as we devoured their world and took The Well for our own devices. None stand against us, for treachery resides in all things and we have set it free."

A Farewell
''Some of you in a previous life may have held childish notions of God and the kingdom of heaven. This ugly representation of a spiritual nirvana was designed to control you, to placate your natural feelings of hatred and rage, to subdue your realization of your place in this universe. By embracing science, you took the first steps towards freedom from this intellectual chains. By dedicating yourself to the development of Argent Energy, you cemented your place in the next age.''

Now let me tell you about the real heaven.

''The real kingdom of the gods is a place that you will never reach, and you should never wish to. No human will ever visit the sacred ground of Argent D'Nur, unless they are made a god by the dark lords. Humanity's only purpose, and reward, is to serve the ascension of the Imperatrix and protect the Crucible. You will be destroyed by the demons, while I will be made a god. My immortality is assured, while you will writhe in perpetual agony at the bottom of the darkest hole in Hell. You will be forgotten. Your life, your loved ones, your achievements and failures are nothing. A blank space in the canvas of time.''

''Thank you for your service. May you rot in Hell.''
