I personally think the Farplane has a greater purpose than what we think... But not sure what the purpose of it was. Basically it is Spira's Heaven... And when you go to the Farplane, and you think of a person you miss who is dead, Their pyreflies form together to recreate them, but only for that moment of you thinking of them. It is a peaceful and calming land of the rested souls... If you think of a person there, and their pyreflies do not form, they have not been through a SENDING by a summoner, or they are not dead, either that or they are a fiend. But I think the Farplane is beautiful in FFX/X2 !
