Argent D'Nur

Argent D'Nur is the thirteenth and final level of the new Doom reboot. There are five secrets located in this level. Elite Guards are absent from this level.

There is little depth to the story behind this location, but still many vague references to it. The apparitions of past soldiers are revealed to the Doom Guy, and historical references show Doom Guy standing as a sort of leader or final-solution among these guardians. In-game references state that hell had a cataclysmic battle with the inhabitants of Argent D'Nur, and was forced to absorb Argent D'Nur entirely into hell so that the demons could finally overwealm and take over the area. It is unknown whether Argent D'Nur was a super advanced human civilization that was wiped out by "hell's armies", or some other advanced species that were wiped out by largely unknown methods.

Whether the Necromancers which were said to lead or sympathize with them were originally from Hell is also up for question. In-game references state that the current "dark lord of the 9th age" came into power by other means and speculation seems to suggest that this age came into being after "destroying the rule of the necromancers of Argent D'Nur".

"The Well" is clearly a source of infinite power in Hell, and it seemed to be fed by the cursed bodies of these necromancers which you are freeing during the section "Argent D'Nur". Usually this happens after every large battle in hell in late-game, after unlocking or freeing the necromancer spirit from the contraption using the "crucible" (a key-like item that is heavily guarded by Hell) item you obtained earlier in "The Necropolis".
