The Crimson Light, a force so powerful that no one has been able to control, is a power that can be used for both good and evil. Ancient legends speak of it as both a gift, and a curse, from Promathia, god of Twilight. Many bold alchemists have gone in search of the Crimson Light, but none have ever returned with even an idea of how to get it. Thousands died, millions were injured and traumatized. It seemed that no one would ever find this power, until just before the Great War. Bastok had signed a peace treaty with San d'Oria to share information on the Crimson Light. Bastokan alchemists and San d'Orian priests did signifigant amounts of research on the Crimson Light, and eventually translated a scroll.
"Ye born of honor and might, knowing both worlds of darkness and light, shall find the strength that is needed to cleanse the world of the shadows of the night." No one amongst either of the great nations could solve the mystery of the scroll.
Two weeks later, a lone Royal Knight of San d'Oria was sent to Bastok to help investigate the recent disappearancs of several Bastokans involved with finding the Crimson Light.
"I am Seijuro, Royal Knight of San d'Oria. I come bearing permission from the king to help in the investigation of the disappearances." The young knight told the guard.
"Very well," the Bastokan guard replied. "you may pass, Seijuro of the Royal Knights." Seijuro was a powerful, yet gentle-hearted member of the Royal Knights of San d'Oria. Although he was loyal to the king, he was still for the people above all else. While on the case, Seijuro discovered one more link to all the disappearances. Every single one of them had Security Clearance on the Crimson Light research that would let them see things that not even generals of either nation could.
"They could have only obtained clearance like that from both the king and president together... what's going on here?" Seijuro said to himself.
"Simple," a girl behind him said. "group A is trying to find the Crimson Light, and group B is trying to hide it." "Wha...?" Seijuro said. "Relax, I'm Ciero from the Alchemists' Guild. I was ordered to aid you in your investigation." The whole thought of having an alchemist help didn't sit well with Seijuro. However, he agreed and they began their search for the missing Bastokans.
Four days after Seijuro and Ciero met, all three cities were invaded by beastmen. Fifteen people died in Bastok, nineteen in San d'Oria, and seventeen in Windurst. The people of all nations were shocked by the timing and strategy of the beastmen, but nothing kept Seijuro and Ciero from working hard on trying to find those who went missing searching for Crimson Light. Time passed, and they both had to escape to neutral territory to avoid the raging war. Their investigation on the missing soon turned towards finding the Crimson Light, once they realized that it might hold the answer to the unexplainable. Time continued to flow, but slowly. Four years after the Shadow Lord was slain and the Great War was over, the bond shared by Seijuro and Ciero during their time together had grown strong enough that they had become parents of a baby boy. This child was half-Elvaan and half-Hume, and resembled Elvaan. He was named Kazu after Seijuro's late mentor. Two years later, another boy was born, and he resembled Hume. Kazu's younger brother was named Kousaten. It wasn't until these two boys were born that Seijuro and Ciero realized Crimson Light was a latent power given at birth, but they did not know who it would be born to. They decided that their new goal in life was to keep their family hidden from the real world, for the chances were great that one of their two sons had the power deep inside of him...
