The curse that Destiny sent in connection to the energy was a malevolent curse that could easily mean the destruction of an army. By all common sense, the addition of the curse [De-Spacito] alone would have meant sure demise.
Destiny had once more believed he overestimated the strength of Kyros and the ability to overcome the curse, much less teach it to the forces.
And yet, Kyros had done the impossible.
The power of Pronto was one of Kyros's amazing skills developed naturally since his perception has always been slower. The curses and seals that were placed on Kyros by Fate were meant for occasions such as this.
And so, the impossible occurred. However, the steps to recovery had already started. Unknown to many, they were already using Pronto, and most of them had recovered from it.
