A nebula entity transforms the Enterprise into the fantasy world of Rukiya's favorite storybook, leaving only M'Benga and Hemmer aware of the change.
After the warp drive fails near a nebula, M'Benga wakes to find the Enterprise transformed into the high-fantasy world of a storybook his daughter Rukiya loves, with the crew playing its characters. Only M'Benga and the telepathic engineer Hemmer realize what has happened.
They learn the nebula is a conscious being that created the fantasy after sensing Rukiya's loneliness, and that it has cured her disease, though the cure will fail if she leaves. M'Benga reluctantly lets Rukiya join the entity as an energy being, and he sees her grown up, calling herself Debra. The ship is restored, and only M'Benga remembers the adventure. The world returned in the fourth season's Once La'An a Time.
