"Hallowed are the Ori."
―The Book of Origin, often repeated by Priors[src]

The Ori (pronounced or-eye) are extinct ethereal ascended Alterans who had near infinite knowledge and powerful abilities that first evolved as a physical species from the Alteran Home Galaxy. The Ori, before ascending, emerged from Celestis. The Ori used their knowledge and power as a justification and a means to demand the worship of mortal beings, when they learned such worship increases the power of ascended beings. They were destroyed by the Sangraal as the Great Enlightenment drew to its end.


Early History[]

"Their power is not what you should question. It's how they use it."
Cameron Mitchell[src]
Main article: Alteran

Millions of years ago, the Ori lived together with the Ancients as a single, united species in a distant galaxy as the Alterans. At some point, however, a split occurred among the Alterans: The Ancients began to devote themselves to science, while the Ori became increasingly religious. This division eventually became so great that the Ori attempted to destroy the Ancients. To avoid a war, which was contradictory to their beliefs, the Ancients departed their home galaxy for the Milky Way.

Even after they left, the Ancients and the Ori remained enemies: Dr. Daniel Jackson believes that the Ori were responsible for the plague that nearly brought the Ancients to extinction in the Milky Way and forced them to leave in Atlantis for the Pegasus galaxy. Both the Ancients and the Ori eventually ascended, and the Ori passed on a religion called "Origin" to the next evolution of humans they created in order to increase their own power, using their ascension and knowledge of the universe as justification for praise and worship, as well as including the promise of ascension to lowers that they never intended to deliver upon. (SG1: "Avalon, Part 1", "Avalon, Part 2", "Origin", "The Powers That Be", "The Ark of Truth")

The Crusade[]

"Great holy armies shall be gathered and trained to fight all who embrace evil. In the name of the gods, ships shall be built to carry our warriors out amongst the stars, and we will spread Origin to all the unbelievers."
―The Doci[src]

In 2005, it was revealed that the Ori do not grant their followers Ascension. They don't want to share the energy that they gain from the devotion of their worshipers. There is a real, physical transfer of energy to an ascended being that occurs through a human being's belief in them. For it to have a measurable effect however, massive numbers of followers are required to relinquish their will. This system of energy transference is one of the reasons the Ancients will not interfere with any life on the lower planes of existence; if the Ancients interfere, they are no better than the Ori. (SG1: "The Fourth Horseman, Part 1", "The Pegasus Project")

While the Ancients stopped the Ori from interfering in the Milky Way and possibly Pegasus, they didn't stop the Ori elsewhere and did not attempt to stop their human followers. Doing so would've violated their rules on non-interference with those on a lower plane of existence. One Ancient named Merlin, however, was aware of the threat the Ori would one day present, and designed a weapon capable of killing an ascended being. (SG1: "Arthur's Mantle") For no explained reason, the Ori never expanded their crusade (or sent even a single prior) to the human or wraith populations in Pegasus, despite knowledge of their existence through their interactions with the Tau'ri.

In 2006, the Ori managed to establish a link between their home galaxy and the Milky Way through a Supergate, and sent four nearly invincible motherships to begin the conversion process. Through Stargate Command and the Atlantis expedition the Tau'ri were able to make a connection between the Supergate and a Stargate in Pegasus, managing to destroy one of the Ori ships. The Ori army though continued unabated, annihilating the Milky Way while converting many civilizations to Origin and destroying those who refuse to convert. The crusade was led by Adria the Orici, an Ori in human form, so as to prevent the Ancients from stopping them. (SG1: "Camelot", "Flesh and Blood", "Morpheus", "The Pegasus Project", "Counterstrike")

However, their real plan to destroy the Ancients cost them much more than they anticipated. When Adria discovered the location of the Sangraal, it was learned that Morgan Le Fay had destroyed the weapon, but preserved Merlin so that he could recreate it when the time came. Merlin, too weak to continue, downloaded his consciousness into Dr. Daniel Jackson. Adria captured Jackson, and hoped to use his knowledge to create a Sangraal to destroy the Ancients so that the Ori would not have to even fight. However, Jackson intended to send the Sangraal to the Ori home galaxy. (SG1: "The Quest, Part 1", "The Quest, Part 2", "The Shroud")

Adria, the last of the Ori

"No! You can't take away my power!"

With the help of SG-1, the Sangraal was sent through the Supergate, along with Adria. At first, the Tau'ri had no knowledge of whether it worked or not; several months after the Sangraal was sent, Adria claimed that their attempt failed, while Ba'al, after taking Adria as a host, claimed that they were killed. Worse yet, sending the Sangraal to the Ori galaxy allowed the Ori army to regain control of the Supergate, and another six Ori warships were sent to the Milky Way. (SG1: "The Shroud", "Dominion")

SG-1 eventually discovered the fate of the Ori, after traveling through the Supergate on the Odyssey. Adria, appearing before Vala Mal Doran from the Flames of Enlightenment as an ascended being, confirmed that the Ori were indeed killed by the Sangraal, however she alone inherited all of their power. Her triumph did not last long: SG-1 exposed the Doci to the Ark of Truth, instantly turning all Priors in the galaxy away from Origin and stripping Adria of the majority of her faith-generated power. In Adria's weakened state, Morgan Le Fay was able to engage her in eternal combat, permanently neutralizing the Ori. With the Ori dead and Adria gone, SG-1 used the Ark of Truth to reveal the truth about the Ori to everyone in the Milky Way Galaxy, ending the crusade that the Ori started. After the end of the crusade, the Ori army returned to their home galaxy where they presumably disbanded for good. (SG1: "The Ark of Truth")


Very little is known of the culture of the Ori before Ascension, though there have been observations of their human followers. The humans created by the Ori live in an agrarian age level of development, presumably to prevent them from becoming a problem (much as how the Goa'uld and the Wraith destroy advanced cultures which could be a threat to them) or realizing they are not gods.

The human followers live within villages run by Administrators. The Administrators appear to possess very broad powers with regards to village administration, such as immolating suspected heretics. One administrator was known to lead Prostration himself. Seevis, another administrator, allowed the local Prior to run it. (SG1: "Avalon, Part 2", "Origin", "Crusade")

Among the Ori's followers, a common saying for greeting is "Above the sun to you." (SG1: "Avalon, Part 2")


"Those who reject the path to enlightenment must be destroyed."
―The Doci[src]

Origin (episode)

The Doci possessed by the Ori standing before the Flames of Enlightenment

Due to the origins of their ancestry, the Ori believed themselves to be the creators of human life. They are aware of the Ancients, but shun them, saying they abandoned the "path", and believe in the opposite philosophy. They claim that not sharing the secrets of the universe to those on the lower planes of existence is an evil act and those who practice it must be eliminated.

The Ori conceived the Origin faith, one that puts them in the center of creation, and wrote down their word in the Book of Origin to be administered to followers through Priors, missionaries and teachers of Origin. The Ori use the Doci, the chief Prior, as their "mouthpiece" for communicating with lesser beings. They are able to possess his body to spread their demands and will. When this happens, they can be identified with fiery eyes. (SG1: "Avalon, Part 2", "Origin")

Though the Ancients were always more powerful than the Ori, due to the greater numbers of worshippers the gap was getting smaller. More and more Ancients, including Morgan Le Fay were becoming worried. Dr. Daniel Jackson suspected that it is because of this difference in strength that the Ancients were able to prevent the Ori from gaining the knowledge that the Milky Way galaxy was populated, and possibly knowledge about the Pegasus galaxy as well. Though they disagree with the philosophy and goals of the Ori, the Ancients will not intercede in the free will of lower species, nor will they prevent "unbelievers" from converting to follow the Ori. If unbelievers don't convert, the Ori will destroy large numbers of the unbelievers - although the Ancients do not seem to prevent this due to their fierce belief in free will. (SG1: "Origin", "Prototype")


"Is great knowledge, power, understanding not enough for you to revere the Ori?"
―The Doci[src]
Main article: Ori technology

Ori technology ranges from the biological to the mechanical, and most, if not all, of their technology is created and used for the purpose of gathering worshipers in order to increase their own power by demonstrating godlike power. Any discovered technology created prior to their Ascension is destroyed with no exceptions, lest their Human worshipers doubt their validity as gods. Since they and the Ancients were one race, it is safe to say their technology would be identical to what the Ancients left behind in the Milky Way galaxy.

Behind the scenes[]

Stargate Wiki has a collection of images related to Ori.
  • Ori derives from "Origin". The original idea was the origin of the Ancients, then Robert C. Cooper looked at the root word for Origin and thought of Ori and that they invented the word "origin", which is the name of the religion that follows them.[1]
  • Ori (/ˈorɪ/) means slave in Estonian.
  • Ori (/ori/) mean stallion in Finnish.
  • Ori means number two (2) in Georgian.
  • Or means "light" in Hebrew. Therefore, making: 'or-eye' into 'light-eye" (i.e. the eyes light up)
  • Ora (very similar to Ori in pronunciation) or Awra means to light or to burn in Arabic.
  • The exact reason behind why the Ori never played a larger role in Stargate: Atlantis is unknown.
