Maykr

The Maykrs are a race of angel-like beings hailing from the realm of Urdak, which first occur in the settings and backstory of Doom (2016), albeit not clearly identified. They are later named and more fully revealed in its sequel, Doom Eternal. They are led by the Khan Maykr. Despite their appearance, the Maykrs aren't angels or gods, instead being a very advanced species who turned themselves into angel-like cyborgs to greatly prolong their lives.

History
In the Ligra Sultagenta, the Night Sentinels' Book of Kings, the Maykrs are said to have first made contact with the Argenta during the reign of King Etrex during a period known as the Time of Grief. Described as "porcelain beings" from a higher realm, they brought gifts of magic and advanced technology which the peoples of Argent D'Nur quickly adapted.

As a result of this contact, the Argenta began to spread out from Argent D'Nur on giant floating city-like ships throughout what they called the "Empyrean Void", which from illustrations in the Ligra Sultagenta appears to be what is otherwise called outer space. At this time they sought to spread the word of the Khan Maykr, which they considered to be an enlightened ideology.

By the time of King Novik and the struggles against Hell in Argent D'Nur, the Khan Maykr was no longer trusted by the Argenta. She had corrupted the Order of the Deag, and its priests now served her interests rather than those of their own people. She is implied to have sent the Deag on a mission into the depths of Hell to lure the elite warriors of the Night Sentinels into a trap; among their number was the Betrayer, who succumbed to the demons' temptations after being flooded with nightmarish visions of the torments his son was facing.

When news of the betrayal arrived, the King bemoaned his ill-advised decision to trust the Deag one final time. He states that they returned to their "mistress" after their ill deed was complete, and there is evidence that they instigated a civil war among the Night Sentinels at her command.

Known Maykrs
At least five Maykrs are currently known:
 * Two which occur only in the form of statues in Argent Breach and Empyrian.
 * One which both occurs as statues in the aforementioned areas, and appears in person in Doom Eternal, possibly in the environs of Sentinel Prime.
 * The Khan Maykr, who is described as their leader.
 * The Father, the progenitor and true leader of the Makyrs. He is said to have vanished.

Aside from named or unique Maykrs there are generic Maykr Drones, controlled by Khan Maykr.
