For other uses of this name, see Adria (disambiguation)
If an Ori were to enter the Milky Way in ascended form it would be fought by the Ancients. To prevent this, they cheated the ascended law by creating one of their own in the form of a human. The Ori chose Vala Mal Doran to carry the child, coinciding with her and the Ver Iscan Tomin's romantic relationship. Both eventually learned from a Prior that Tomin was unable to conceive a child -- and it was the Ori's -- not his.
Vala carried the child for approximately nine months in Ver Isca, but it was born aboard an Ori warship while the fleet was en route to Chulak in the Milky Way Galaxy. A Prior named her "Orici." Tomin called her a "truth seer," knowing she would see through Vala, who did not truly believe in the promises of the Ori.
Though the Orici's gestation occurred at a normal human rate, she was genetically engineered to reach full maturity in a matter of days following birth. Vala, displeased that she was separated from her daughter immediately after giving birth, was eventually granted an audience with the infant. She renamed her Adria, after her formidable stepmother.
Because the Ori's knowledge of the universe is supposedly limitless, the Orici is not a true Ori. She is as close as can be created in human form. The knowledge in her mind un-spooled as her physical body matured, causing headaches during the growth stage.
Adria's power is at least on the level of that of a Prior, though she is not one of them. She is between the Doci and the Ori in status, and many of her abilities have yet to be gauged. Adria claims that despite the fact that she is essentially Ori, there are parts of her that resonate positively to being Vala's daughter. Despite this, she resists attempts to be humanized, and she is not sympathetic to her mother's beliefs. Instead, Adria hopes that Vala will eventually come around to see that the Ancients -- not the Ori -- sap energy from those on the planes of existence beneath.
Shortly after SG-1 succeeded in wiping out the Ori using Merlin's anti-Ori weapon, Adria herself managed to ascend. This left her the sole beneficiary of the energy directed at the Ori by their worshipers, making her incredibly powerful. But when the team found the Ark of Truth and removed the power of worship, Adria was suddenly brought to the level of any other ascended being. The Ancient Morgan Le Fay engaged her in combat, and the two (evenly matched) presumably will remain locked in battle for all eternity.
