Leon St. Gabriel was born to a minor, but respected, noble family in Southern Spain. Although his birth was at first a joyous occasion, a shadow quickly descended on the household as it became clear the family's youngest son had hemophilia.
Leon's birth should have assured the family's future. Although the Don already had one son, Diego, a second one would ensure that should the eldest die the family would go on. The other three children in the family were all girls.
But with the realization of Leon's condition, chances were slim that he would live to reach adulthood. Even if he did, his condition would make it difficult for him to rule effectively if that became necessary.
Don Isidro responded to the tragedy by withdrawing from the sickly child, focusing his attentions on Diego. His wife, in turn, dedicated her life to making sure Leon grew up in as safe an environment as possible.
As they grew up, both boys chafed under the attentions of their parents, and drew closer as a result. Diego tried to help Leon engage the world, finding ways to escape the Keep and experience the adventures healthy people take for granted. Leon, for his part, helped Diego with his studies. The elder St. Gabriel was not as smart as his little brother, and the two would spend hours reviewing their lessons or studying language.
When the Pope called for a crusade to free the Holy Land from the barbarians, Diego was quick to answer the call. The St. Gabriel's had always been a pious family, a feeling that had grown with Leon's birth. The family believed that God was testing them and that by answering the call and earning his Grace, perhaps Leon would be cured.
While Diego prepared to depart, Leon was informed that he would remain in Iberia. Because of his condition the chances of him making it through France alive were slim. No one, not even Diego, believed he could survive the hardships of the desert kingdoms.
In the months leading up to the departure, Leon secretly made plans of his own. Although he had no illusions of his usefulness in combat, he realized that he could still contribute to such a Holy cause with his knowledge and language skills. He was fluent in Arabic and a talented strategist, and when the caravan left, Leon left with them.
Leon had left behind clues that he intended to head for London. By the time the truth was learned, it was too late to do anything about it. The brothers were already on board a ship and en route. Turning back was not an option, and Diego was secretly pleased to have his brother with him despite the risks.
Diego fought well over the next few months. His skills with the sword earned him a reputation among friend and foe alike. With Leon's tactical planning he won several key victories and the two brothers seemed destined for greatness.
It was when the two St. Gabriels were returning to there camp that Leon exchanged words with a drunken knight. A fight broke out and the young lord smashed his fist into Leon's nose and causing it to bleed.
With anyone else, this would not have been a big deal, but because his blood wouldn't clog, and with no way to apply pressure to stop the bleeding, it was clear that Leon would soon bleed to death. A captured Iman in the camp quickly began treating the young lord, and through his care began to recover. When the local priest discovered what was happening, he had the Muslim dragged away and executed, and told Diego that his brother was in God's hands now.
"Pray for forgiveness for resorting to such heathen ways. Pray that your brother does not die for your sins."
Leon died the following morning.
Diego was destroyed. He had seen his brother getting better, and realized that it wasn't until the priest interfered that things began to look bad. God had smiled on the "heathen" and ignored the Christians. Diego for the first time began to question his faith.
Enraged with the priest's callousness, Diego slit his throat and fled into the desert. He wandered for three years, learning the language and customs of the people. Diego would later say that during these years God (or Allah) was forging him physically, mentally, and spiritual, like a fine sword. It is a personal time, and he seldom speaks of it.
Eventually, Diego's ability with the sword brought him to the attention of Abdul bin-Kali of the Children of Haquim. bin-Kali took Diego in, and began grooming the young lord for the embrace, helping to hone his martial skills while addressing the spiritual wounds he suffered from.
Diego converted to Islam shortly before he was embraced. As was custom amongst both the Assamites and the Muslims, he changed his name to begin his new life. However, he chose to adopt his brother's identity, to try and live the life he was denied.
Leon is struck down in the catacombs of Paris at the dawn of the 21st century by his first child, Donovan; a victim of the Schism that would shatter the Children of Haquim.
