But how do we describe the Void, from our perspective? The closest thing we can come up with is a black hole. Google describes one as
“a region of space having a gravitational field so intense that no matter or radiation can escape”.
Many Final Fantasy villains attempt to bring a Void on their worlds. The etymology of Final Fantasy III’s Cloud of Darkness “a dark cloud or dark nebula is a type of interstellar cloud that is so dense that it obscures the light from the background emission or reflection nebula or background stars.”
A dark nebula is otherwise a Black Hole, and the Cloud of Darkness manifests from within “the Void”.
Black Hole is an enemy ability used by Zeromus’s Malice, Creator, Mysterious Girl, Omega (Wii/PSP versions only), and Lunar Bahamut (smartphone versions only). It removes all positive statuses from the party.
Exdeath obsessed over the Void. His move set in Dissidia proves this.
In Final Fantasy V, Exdeath has two moves which allude to black holes: Vacuum Wave (which inflicts Sap, lowering HP) and Graviga (which reduces HP by 7/8). In Dissidia Final Fantasy, Exdeath can actually summon a black hole as his move.
Also in Final Fantasy V, the Phantom/Mirage Village, was caught in the Interdimensional Rift for 1,000 years. The Interdimensional Rift “is a bizarre mishmash of dimensions between worlds”. This could be referred to as Event Horizon, the boundary of the region from which no escape is possible.
The magical spell Gravity “cuts an enemy’s HP by a specific amount, usually by 50% or 25%”, but are not lethal (except for in Final Fantasy IX, Final Fantasy XII and Final Fantasy Tactics, which “are based on the target’s maximum HP as opposed to remaining HP in other installments”).
