Onaya, who took the corporeal form of a female humanoid, was also a "muse" to the individual she associated with, allowing them to free creativity from their mind that they might be unable to tap into normally. A side effect of this was that Onaya's draining of an individual's neural energy eventually killed them. The entity told him that what it gave the people it "touched" was a type of immortality. They and the works they created with her as their muse would be remembered for generations. As Sisko raised his phaser, Onaya transformed into her non-corporeal state and left the station.
