You couldn't reach the Farplane...Yuna
Ghost is an enemy in Final Fantasy X found in the Cavern of the Stolen Fayth. Ghosts are also seen in a vision Tidus has at the Farplane gates. It is a gray, ghostly humanoid with long arms, sharp claws, two big horns, enveloped in white mist.
ghost is the soul or spirit of a deceased person or animal that can appear, in visible form or other manifestation, to the living. Ghosts are generally described as solitary essences that haunt particular locations, objects, or people they were associated with in life, though stories of phantom armies, ghost trains, phantom ships, and even ghost animals have also been recounted.A
