Force.....mmm....Wild Individual Guessing here but, in Shin Megami Tensei, there's Almighty spells, strong, destructive, purple spells that ignore elemental resistance.

Normally they are represented by the Megido- line of spells. Megido, Megidola, Megidolaon. However, in Persona 2, they were instead represented by 2 lines of spells: Zan and Zanma, that normally are Force spells in the other games, and Gravity, which in P2 is esentially a multi-target Almighty spell.

And to put it short: In Persona 2, Gravity spells, represent the Almighty element, which is esentially Non-Elemental. Coincidence? Maybe, or maybe not.

Perhaps there's non-elemental Dust, much stronger than other Dust types though with the cost of not being elemental in any way. Maybe it's harder to obtain than other Dusts. Either that, or it's Darkness.
