Night Sentinels

The Night Sentinels were an order of holy knights that protected the Argent D'Nur and once stood against the armies of Hell in the realm of Argent D'Nur eons ago. They are led by King Novik.

During the Sentinel Prime Civil War, the Night Sentinels were split into two factions: Loyalists and Order of the Deag. The Night Sentinels of the Order of the Deag will be enemies of the Doom Slayer in Doom Eternal.

Background
According to passages from the Ligra Sultagenta, also known as the Book of Kings, the race of the Night Sentinels called themselves the Argenta. They arose on a world that was impaled by a giant impactor known as the Cosmic Spear, which unleashed the beings of immense power known as the Elemental Wraiths (also called the "Firstborn" by the Argenta), and began the evolution of life on their planet. They were driven by the hostile environment and the power of Wraithcall to take up arms and in time created a highly advanced warrior culture, defeating giant magical creatures known as the Ancestrals in order to secure their place in the world of Argent D'Nur.

They crowned a series of warrior kings, beginning with King Ormero the Father. All kings of the Argenta were required to be warriors and were expected to lead from the battlefield in times of war; those who could not were deemed unfit to rule.

The Night Sentinels were formed by the first king of Sentinel Prime, Ormero the Father. They became the guardians of the Wraiths, and acted as both their holy servants and a bridle for their awesome power. However, due to the power of the Wraiths who could corrupt normal humans into monstrous beings, the Night Sentinels also acted as a control measure to the Wraiths to prevent their power from wreaking havoc.

The Order of the Deag was founded as a priesthood to tend to the Wraiths, which the people of Argent D'Nur both worshipped and feared. Through immersion in the Wraithcall, the people of Argent D'Nur mastered both magic (actually wraith energy) and technology, and combined them. Together, these made the Night Sentinels, the core of the legions of the Argenta.

The Khan Maykr saw great promise in the flourishing Argenta, and made herself known to Sentinel Prime. She and the Makyrs would aid them in their war against Hell and grant them the gift of Argent Energy to fuel their armies.

A great time later, during one of the many invasions of Hell, the Night Sentinels discovered Makyr factories in Hell being built by Sentinel slave labour. They found that Argent Energy was actually made from the souls of those slain by the Demons of Hell, and that the Khan Makyr had made a deal with the Dark Lord of Hell to gift them the factories to refining it and access to all the worlds under Makyr guidance, in exchange for supplying Urdak with a majority of Argent Energy.

When the Night Sentinels returned to Argent D'Nur and spoke of their findings, a divide was split between the people. While one side was horrified by the discovery, a majority of the populace, having benefited from Argent Energy and being grateful to the Khan Makyr who promised the faithful eternal life in Urdak, to no issue with the revelation.

Thus the Night Sentinels, comprised of the free people of Argenta and the Slayer himself, went to war against their own people, returning to the way of the Wraiths even if it diminished their armament without Argent Energy. Civil War rose between them and the Ascended Empire, those who believed in Makyrs and comprised of the faithful and misled, the Marauders and those who wielded the power of Hell.

The Night Sentinels with the aid of the Slayer proved to be much too powerful to defeat, so the Khan Maykr recruited the help of the Dark One and his legions of Hell to the cause of the Makyrs, with the help of the Order of the Deag who pretended to aid the Night Sentinels and their King while being secretly loyal to the Khan.

The Night Sentinels were imbued with Wraith energy and proved fierce opponents to Hell's legions and, according to the Ungmar Codex, almost triumphed over Hell but were betrayed by a member of their order and their High Priests. The Betrayer struck a bargain with the priest, Deag Grav, for the return of his son who had fallen in battle, and he led the priest and his cabal to the source of the Night Sentinels' power, the Elemental Wraiths. Daeg Grav cursed the Wraiths while they slept, and the Hell priests stole their energy for their own devices. Argent D'Nur was defeated, their realm absorbed by Hell, along with the Argent Energy that led to the creation of The Well, and the Betrayer's son was resurrected as the Icon of Sin.

The most disillusioned of Night Sentinels defect to the Order of the Deag and the Makyr, and once they died they were revived as a Marauder.

Giant statues of the sentinels can be seen in Argent D'Nur, while two smaller statues labeled 'Ancient Sentinel' can be found in Samuel Hayden's office on either side of a statue of the Praetor Suit.

Appearence
The Seninels or Argentians are arguably human - and visually they very much resemble people. It is unknown if their physical abilities are the same as humans or differ in any way. Regarding the facial features of the people of Argent D'Nur they appear somewhat narrow, with clearly visible cheekbones and distinctly slanted eyes, being tilted inwards. The skin, hair, and eye colours of the sentinels seem to also match those variations seen in Earthborn people as well.

Culture
The Night Sentinels adopt warrior culture and deems only the strongest warrior can rule Sentinel Prime. The King of the Sentinel Prime must be a warrior that can lead troops to battle not sitting behind the throne. Any kings who are unfit to lead troops will be disposed of and replaced with one that is more capable.

Faction
There are two factions within the Night Sentinels
 * Loyalists: Night Sentinels who oppose Hell's Legion and the forces of the Khan Maykr.
 * Order of the Deag: Night Sentinels who defected to the Khan Maykr side, they are opposed by the Loyalists.

Weapons
Night Sentinels wield swords that can cut through demons with ease. In Doom Eternal, they wield a spear with Argent Energy as the tip. They may also use Super Shotguns, as Marauders are always seen with one.

Known Members

 * King Ormero The Father (Founder)
 * King Etrex
 * King Novik
 * Doom Slayer
 * Betrayer


 * Marauders (Defected)

Discrepancies
It is unclear where Argent Energy actually comes from. The Well appears to siphon Argent Energy from the Elemental Wraiths themselves, and the people of Sentinel prime named themselves the Argenta, but there are also references that suggest the Khan Maykr gifted the Sentinel people Argent Energy as a way to earn their trust.

Trivia

 * It is possible that the Night Sentinels were the mysterious ancient martians mentioned in other Doom games. The martians likewise have been described as resembling humans and having an advanced civilisation on Mars a long time ago, now buried underground. In Doom Eternal the Night Sentinels had a civilisation on Mars.
 * In Multiplayer, players can use the Templar Armor, the wearable equivalent of the Night Sentinel armor.
 * The Armor that the Night Sentinels use is visually inspired by 15th Century Gothic Plate Armor, used by the Holy Roman Empire.
 * Their Helmets are also inspired by the Great Helm, which was used by 13th - 16th Century European Knights.
 * King Ormero's name is an anagram of Romero.
