The Abyss Order is a mysterious, but powerful legion of monsters from the Abyss who are the enemies of both humanity and surface civilization, and thrive in many corners of Teyvat. They are one of the main antagonistic factions in Genshin Impact.
Because most members of the Abyss Order reside in the Abyss, little is actually known about them by Teyvat at-large, other than that they hold a strong hatred against humans and desire to overthrow the world ruled by the Archons.
Their size, hierarchy, membership, leaders, degree of power, and threat level are largely unknown currently.
According to Diluc, "there's more to [the Abyss Order] than just some Abyss Mages" when he's warning the Traveler and Paimon not to underestimate them, implying there are monsters in the organization that are stronger and more dangerous that were not yet introduced. While this was later confirmed by the introduction of Abyss Heralds and Lectors, it is unknown if there are other members that have yet to reveal themselves.
The Traveler's sibling, who eventually leads the Abyss after becoming separated from the Traveler — sparking the Traveler to embark on a journey across Teyvat.

The Order usually conscripts Hilichurls to do their work.
In the quest We Will Be Reunited Paimon and the Traveler begin to learn more of the truth behind the foundation of the Abyss Order: around 500 years ago, the fall of the Eclipse Dynasty led to a cataclysm that destroyed Khaenri'ah. The Abyss Order grew out of that destruction, formed of people from Khaenri'ah who sought revenge for that event, through the destruction of the Archons.
In the present, the Abyss Order is led by the Traveler's Sibling, who was separated from the Traveler by the Unknown God and traveled Teyvat first. It is unknown how they managed to become its current leader, but all of their subordinates revere them, addressing them in a royal manner.
Currently, the Abyss Order is attempting to execute their Loom of Fate operation. To this end, they plan to use the ancient technology behind the "Field Tillers" from Khaenri'ah, and they searched many Ruin Guards hoping to find the eye of the very first one. With it and the Defiled Statue underneath Mt. Aocang, they intended to use both of them on Osial to create a mechanized god they could control. The eye was found by the Traveler and Dainsleif at Stormterror's Lair, but Dainsleif opted to carry it with him rather than trust it to another party. When the pair returned to destroy the statue, they were met by an Abyss Herald, who was later saved by the Traveler's sibling. The status of the operation is currently unknown, as Dainsleif chased after the two with the eye in his possession, and without him, the Traveler had no idea how to destroy the statue.
- Background stories that may related to the Abyss Order are told in some artifact set and weapon lores — notably that of Arundolyn, Grand Master of the Knights of Favonius, who led an expedition against the monsters that spewed forth from Khaenri'ah. While he survived, his friend and companion Rostam perished in battle.
- Rostam was mentor to a person known as the White Knight, later known as the Bloodstained Knight. After his violent path caused others to shun him, he continued his battle against the monsters in Khaenri'ah and ultimately perished. After death, however, he learned about the injustice behind Khaenri'ah's destruction, that caused the people of the land to be cursed and become monsters.
