I figured anyone who likes FF enough to join a site like this would've known that it was so named because "Ysatnaf Lanif" is the name of a powerful deity and playing the games backwards while chanting his name to the Final Fantasy theme (not Prelude) backwards will destroy a black hole, and once all of the black holes are destroyed (the point of the series), Ysatnaf Lanif will once again come forth and lay waste to humanity.
