Early life:
Raziel Auditore was born into the Roman Catholic Family of Mother, Elizabeth Tudor, was born in a wealthy family of the previous King of England, Henry VIII. Shamed of her father's disloyalty to her mother, Elizabeth fled England and sought refuge in Rome. She was wandering Rome, trying to find a home to buy, when bandits tried to mug her. Raziel's father, Domonic Romano, came in for the rescue, killing the bandits and getting Elizabeth to safety.
She was immediately drawn to her savior, but was disappointed when he left. Days later, though, she found trails of murders that matched his style. Although she never could follow him, he followed her, growing fond of her. He followed her back to her house and showed himself to her. Delighted, she instinctively hugged him, but then blushed. He held her closer, whispering who he was and the dangers of being in love with an Assassin. Eventually, he be wedded her in a the Vatican church and she gave birth to Raziel.
Against Domonic's judgment, Elizabeth wanted their son to be part of the church, saying he would be safer there. During Raziel's progression within church, his father secretly trained him in the art of the Assassin. Raziel dedication to his father was highly noted, and he became a self-proclaimed Assassin at an early age. On one mission, he finds a relic staff (unbeknownst to him, is one of the Pieces of Eden). However, during his escape, knights (actually Templars) ambush him, taking the staff. He fought back, killing all but one.
The last knight slashed Raziel's right eye with the staff, releasing some power unknowingly. Even wounded, Raziel quickly gets the advantage and prepares to kill the knight. Before his death, the knight tells him that they had kidnapped his father. Raziel found his father in a dungeon, beaten, bloodied, and dying. His father uses his last words to tell him the secrets he needs to find out about his heritage, and the secrets about the Templars, Eden, and the Assassin Order. Knowing Raziel could not break his shackles, his father demands him to leave and protect the family.
Reluctantly, he runs back home and cries into his mother's arms. Raziel did not stop his studies, though. He eventually became part of the College of Cardinals, and because of his loyalty and dedication, he was crowned Pope. The people of Rome admired him for he predicted outcomes of different natures with his "God's Eye". The Church saw him as having truly Holy powers of the Lord. Raziel dug deeper into his family history, and finally found old journals and letters. The information was about a past relative named Ezio Auditore. He found out sensitive information about the Church and Templars, as well as the Pieces of Eden and his father's death.
Not wanting to believe that the Church could part of such a cruel order, he continues being Pope. When the Borgia family came back to Rome, they sought the Vatican where Raziel stayed. Raziel had read about several Borgias in Ezio's journals, which made him uneasy to see them. The Church's archbishops and Templars follow the Borgia family up to the Pope. Raziel is told everything he feared. The Church was working with Templars and the Borgias, trying to reform the earth in their image using the Apple of Eden. Thereafter, he flees, leaving the Vatican and finds the Assassin Order.
The Grand Master at the time already knew who he was and immediately took him in. Due, to his rare gift, Raziel went up the ranks quickly. He is pronounced Grand Master when the previous one is killed in a Templar assault. At the age of 20, Raziel is given the responsibility to run the entire Assassin Order. With it, he seeks out revenge for his Grand Master, and his father.
He finds several sets of armor that was worn by Ezio, several weapons, and Leonardo da Vinci's schematics for a device within the hidden-blades that would replace the single-shot pistol. He combines the attires together to form a unique looks, as well as making a personal touch by wearing a black bandana mask with stitching across the mouth.
Raziel soon marries a woman named Amelia and has twins, Leonardo and Lucia. Not wanting his children to be unprepared, he moves his wife into the Assassin's Guild in Monteriggioni at Villa Auditore and hides her and the twins within the hidden chamber underneath; training them as Assassins. He now operates the Assassin Order from within the mansion. In addition, he has taken the last name off his ancestor Ezio Auditore in honor, still seeking out the Templars.
