There are, in fact, two major prophecies mentioned in "Operation: Cloudbreak". It's these two prophecies that Ra Ji-tae used to decide to form a team that will at least defy it from totally putting the country in annihilation by the Black Cloud Vessels. He used one of these major prophecies to seek out someone from the Red Fire Caster faction who could fulfill it. He learned about the Red Fire Caster named Nae Hyon-jun. But before he was able to do so, he discovered something about the last White Fire Caster who was believed to have died 80 years prior. Ji-tae's search for the truth about it led him to find Elena Grace Chon (given the shorter name Chon Re-na) and eventually recruit her to become a part of the Cloudbreakers team. This made him realize that in order to end the long feud between the White Power Casters and the Red Fire Casters, he would need both Hyon-jun and Re-na to fulfill the prophecy with regards to that. Of course, they all knew it's going to be a dangerous mission, and one of them might die from doing so. It was said to be the price of defying what was in the prophecy. Question is: could they defy the prophesied death, as well? Or will the cycle continue?
