It appears very large in the sky, evidencing it is either bigger or closer to the planet than Earth's moon. One of the consumed regions of Argent D'Nur Corpses of Titans can be seen sprawled in some areas. Birds can sometimes be seen in the distance and the Doom Slayer encounters a 'Sentinel Beast' in the form of a wolf, but otherwise the only signs of life are demonic. The environment is dominated by conifer trees, grasses and mosses.

The sky has a blue-green hue, sometimes lit by streaks of green lightning. The locations visited in-game show a dramatic, craggy landscape with numerous mountains and rocky formations. In Doom Eternal, the non-consumed parts of Argent D'Nur show a rocky terrestrial planet with a climate similar to that of Earth. Of the Sentinels in Hell, the only survivor was the Slayer. For this his name was cursed and he became known as 'The Betrayer.' ДЄrgent D'Nur fell to the forces of Hell that day, with many regions of the planet sucked directly into Hell's blasted lands and the Wraiths imprisoned in the Well. Unknown to the Night Sentinels, the priests of the Order Deag had also thrown in their lot with the Maykrs, and as the Sentinels enacted their plan to destroy the great soul-factories of Hell, they were twice betrayed: firstly by the priests, who scattered the Sentinels in their Atlans all across the surface of Hell and left them to their fate, and by one of their commanders, Valen, who was compelled by the torment of his son to grant the Order Deag access to the slumbering Wraiths. Those traitor Sentinels who fell in battle were simply raised from the dead through Hell's power, a process that corrupted them into undead monsters known as Marauders. Their overtures to their people about this horrific discovery fell on deaf ears, and the Sentinels soon found themselves embattled with their disbelieving kin as a civil war erupted, the Sentinels loyal to the King and Wraiths on one side while many ordinary people and a number of traitor Sentinels sided with the Maykrs. ДЄs the war with Hell continued to rage, the Night Sentinels made a shocking discovery: Argenta slaves working in the bowels of Hell, raising vast towers that processed innocent souls into that same marvellous Elixir that had so benefited their society. The Night Sentinels were among the few to reject this new marvel, seeing it as interfering with their traditions and suspecting a substance drawn from the enemy. Through the use of a formulation developed by the priests, strength, wisdom and eternal life could be granted, as well as an incredible source of power for machines and weapons. The war with the demons led to the discovery of what was called the 'Essence' or 'Elixir,' Argent Energy, by Argenta priests studying fallen demons, and while initially this was seen as a possible weakness that could be exploited, it soon proved more useful. Shortly after the arrival of the man who would one day be known as the Doom Slayer, forces from Hell attacked Argent D'Nur, emerging at the holy city of Taras Nabad, but thwarted, at great cost, by the might of the Night Sentinels. While they still venerated the Wraiths, they came to regard the Maykrs as the true gods, particularly their leader, a creature known as the Khan Maykr.

This led to a powerful civilization which spread throughout the galaxy, conquering many worlds. The creatures offered not just strength or technology, but an eternal reward: those who served them would be granted an afterlife in the realm of Urdak, alongside their loved ones. The Maykrs sent envoys to Argent D'Nur and offered to bring order to their world. The Argenta would later encounter another race of powerful beings, the Maykrs. The Night Sentinels served as their protectors while the priests of the Order Deag would worship and venerate them. Thus they formed a warrior society, led by kings who were required to lead their troops in battle to be regarded as worthy, with the Wraiths as their patron gods. The Wraiths possessed powerful abilities which they granted to the Argenta, who saw these gifts as magic. Soon after the impact, from the wound torn in the planet emerged the angelic creatures known as the Wraiths, who spread across Argent D'Nur as their immense power, known in Argenta legends as the Wraithcall, seeded life to the planet, starting with a race of giants called the Ancestrals and then the first men. Millions of years ago the planet of Argent D'Nur was dormant and lifeless until a massive crystal-like object known as the World Spear mysteriously arrived from the depths of space and crashed into the planet with enough force to pierce it from pole to pole.
