Four Horsemen of the Apocalypse

"Should the first four of the Seven Seals of Revelation be broken, from the horizon shall come four beings riding on a green, red, black, and pale horse. They shall bring with them many plagues, conflict, hunger, and death as they are the harbingers of Earth's Last Judgement."

- Shiva, regarding the Four Horsemen

The Four Horsemen of the Apocalypse are a quartet of infamous demiurges recorded in the Book of Revelation, tasked by the Abrahamic God with the duty of heralding the Armageddon, releasing END onto different planets and universes, including Earth.

They are the White Rider (Pestilence), the Red Rider (War), the Black Rider (Famine), and the Pale Rider (Death), with the Pale Rider being the leader of the group.

Summary
The Four Horsemen of the Apocalypse are one of the most prominent Biblical figures other than the devil, alongside the antichrist and the Beast themselves.

They were said to be the first beings sent by Jesus or the devil to bring death to the majority of humanity on the Last Judgment and they are described as four men riding a white, red, black and pale horses, who represent Conquest (or Pestilence), War, Famine and Death respectively.

History
"The Apocalypse is a job for the professionals."

The Four Horsemen of the Apocalypse are demiurges - Half-Archangel offsprings of the Archangel Raphael, who represents the primordial despair of Nothingness. Unlike other demiurges, their only parent is Raphael as they were directly born from his despair over the actions of humanity.

Each of them were born in the earliest day of human civilization, back during the age of Adam and Eve and their descendants with their birth being closely connected with the primordial humans: War was born when Cain first attacked Abel, Death was born when Abel took his last breath, Famine was born when Cain was marked with his infamous marking, and Pestilence was born when Adam, Eve, and their remaining children mourned for both Cain and Abel.

The moment they were born, they were summoned to the Abrahamic God and were tasked with the duty of heralding the Armageddon, releasing END onto the mortal world so that the world may be born again more beautiful, which they accepted with the greatest of honor.

Their first mission was in Earth, with them marking the end of the Edenith era. However, due to the fact thirteen of the original Nephilim managed to survive the Deluge despite the angels' direct order, their mission was deemed unsuccessful. Embarrassed, the four of them vowed to one day killed the last of the original Nephilim and end the remnants of the Edenith civilization once and for all.

Afterward, they continue their duty, heralding the end throughout Creation, bring forth the end to countless planets and universes, as well as the species and civilizations living within them.

At some point in history, the four of them founded the Apocalypse Alliance, consisting of gods and mythological figures associated with the apocalypse within multiple mythologies and civilizations across mortal world as means of minimizing the paperwork for both themselves and the Abrahamic Heavens. However, unknown to them, it quickly turned into an organization that served the purpose of decelerating their world's inevitable destruction by any mean possible, regardless of the sacrifice.

According to Raphael, the Great War was supposed to kick off Earth's own Armageddon, but due to the involvement of the Three Factions, the Four Horsemen were unable to be summoned and the Earth's apocalypse was put on an indefinite hold.

White Rider
"Then I saw when the Lamb broke one of the seven seals, and I heard one of the four living creatures saying as with a voice of thunder, "Come." I looked, and behold, a white horse, and he who sat on it had a bow; and a crown was given to him, and he went out conquering and to conquer."

- Revelation 6:1 - 6:2

Red Rider
"When He broke the second seal, I heard the second living creature saying, "Come." And another, a red horse, went out; and to him who sat on it, it was granted to take peace from Earth, and that men would slay one another; and a great sword was given to him."

- Revelation 6:3 - 6:4

Black Rider
"When He broke the third seal, I heard the third living creature saying, "Come." I looked, and behold, a black horse; and he who sat on it had a pair of scales in his hand. And I heard something like a voice in the center of the four living creatures saying, "A quart of wheat for a denarius, and three quarts of barley for a denarius; but do not damage the oil and the wine.""

- Revelation 6:5 - 6:6

Pale Rider
"When the Lamb broke the fourth seal, I heard the voice of the fourth living creature saying, "Come." I looked, and behold, an ashen horse; and he who sat on it had the name Death; and Hades was following with him. Authority was given to them over a fourth of the earth, to kill with sword and with famine and with pestilence and by the wild beasts of the earth."
