Sephiroth hadn't been within the first gathering of Heroes but having taken to the streets tonight the foreboding way that the clouds had spiraled over the top of where the Observatory was, coupled with that first blinding flash of lightning had been direction enough for him to sprint in.

"That crystal, is one of four that had been recovered from the Magitek Facility more than a year ago." A somewhat out of breath comment from behind the gathering is heard as Sephiroth strode towards the battle lines, his katana-like sword out on his left-side already- though hardly the size of the Masamune which still remained at home atop it's wall mount. He hadn't the Jobs to wield that sword right now.

"Last year, the moogles used one of them in an experiment for Kalki, to gauge how she might be able to control Heroes of Light...their goal to resurrect their long-dead King. In the months afterward, it was discovered that the black crystals yield an unknown amount of power where it comes to resonating with our own crystals; by extension...our very states of being."

He took a long look over the situation before him as Sephiroth slipped into a battle stance, almost grimacing as he identified the Hero caught within the middle of all of this.

Cloud. He would have shouted, had he any hope that the words might reach the other man from his world...one as interconnected with his own future as surely as JENOVA might be.

"We're not going to be able to help him. There is only one thing that's to be done."
