Excuse the Double-Post...
I guess I'll just move on to Diablos...
The way, I see it, Diablos is an extra-dimensional entity that resides within a dimension that is so saturated with extremely heavy gravity or 'dark matter', that the very air (if any) is a dense black mass. It could be that Diablos resides either in the Dark Latern itself or in a dimension that is connect vicariously to the FFVIII world via the Dark Latern.
As Diablos is summoned from this dimension he sees the target, and hurls a "small" amount of the dark matter from his dimension unto the target crushing it with incredibly dense gravity.
I find this interesting because I ponder what else could survive in a dimension like that and is this connected to the Forbidden Time Para-Magicks like "Demi"...
