A Definian
The Definians (デフィニア, Definia) are a race of beings in Xenoblade Chronicles X. They are a humanoid alien race; a tribe of women with high stealth skills and experts in infiltration by disguise, due to their ability to manipulate others' perception. They often use Ganglion weapons and equipment, and are responsible for many of the minor antagonisms of New Los Angeles.
Description[]
"A unique race composed only of females. Definians possess the ability to manipulate other organisms' visual perception, and can make themselves appear to be anyone that they wish. This disguise, however, will only remain in place so long as there is no physical contact between parties.
While the Definians' talents make them perfect spies for the Ganglion, they do have a well-earned reputation as fearsome Skell pilots."
Fortun[]

Fortun with HT665: Erio
Fortun is the queen of the Definian race and is known to wield ancient galactic knowledge. She addresses the other Definians as her daughters. Her affinity chart profile identifies her race as "Fortun".
Her appearance is of a floating orb surrounded by holograms.

Trivia[]
- Unlike other Ganglion races, the battle theme "Black Tar" plays instead of "The Key We've Lost" or "z29ba2t0t1l301e17" while fighting a normal minor Definian.
- Each Definian sister has a name and classification derived from different major arcana cards in a Tarot deck, something TW772: Trinn directly references during Rites of Ruin, when declaring herself to be the Tower.
