Vali cel Tradat

"Once, your Creed was as vital to me as air and water… but when the Turks marched into Wallachia and you Assassins did nothing to stop it, how could I continue to believe?"

- Vali's last words.

Vali cel Tradat (unknown - 1511) was a noble, former Assassin and member of the Templar Order.

Having served the Assassin Order for around a decade, Vali left the Assassins after they made a truce with the Ottomans; the same people who had humiliated his people, conquered Wallachia, and murdered his secret idol Vlad Tepes. Feeling betrayed, he joined the Templars, striving for vengeance against the Assassins and Ottomans.

In 2012, his genetic memories were used as an Animi Avatar by the Templar company Abstergo Industries, for the training of their Animus recruits, under the title of the Sentinel.

Assassin life
Born as a noble in Wallachia, Vali joined the Assassins in his early twenties. He remained loyal to the Creed for almost a decade, until the Assassins called a truce with the Ottoman Sultan, Bayezid II.

Believing that truce was traitorous to his people, since the Ottomans had shamed them, conquered their homeland and even murdered his role model Vlad Tepes, Vali left the Order to join the Templars and seek revenge on not only the Ottomans, but also the Assassins. Due to his Assassin training, Vali was soon deemed to be one of their most valued and feared killers.

Stakeout
Being an experienced agent for the Templars, Vali had taken the lives of many Assassins. However, an Apprentice caught on to his actions and spoke to their Mentor, Ezio Auditore, who had journeyed to Constantinople.

Arriving at a small area and using his Eagle Sense, Ezio discovered evidence of Vali's recent murders. Suddenly, as he was spotted running along the rooftops after he had assassinated an Ottoman guard, Vali began to flee rapidly while making passing remarks, trying to escape from Ezio.

Later, as Ezio's Apprentice attempted to air assassinate him and failed, Vali called out for help, spurring some Byzantine guards to aid him, which provided the distraction that would allow for his escape.

Death
Vali later managed to create a diversion, by capturing two Assassins and containing them under Byzantine guard, in order to give him the time to try and infiltrate the main headquarters of the Assassins, which succeeded in distracting Ezio from his true ambition. After Ezio had freed the captives, Vali ordered Byzantine forces to attack the Galata den, with the fight ending with heavy losses on both sides.

Soon afterwards, Vali and Ezio had a brief encounter, which resulted in his attempt to escape. However, he was soon stopped in his tracks by an Apprentice, who emerged from the rooftops and leapt down to assassinate him, this time proving successful.

Before he passed, Vali explained his actions and why he had abandoned the Order, claiming that he could not believe in a cause that had betrayed him. Once he had said his peace to the two Assassins, he gave his last breath.

Final words

 * Vali: Once your Creed was as vital to me as air and water… but when the Turks marched into Wallachia, and you Assassins did nothing to stop it, how could I continue to believe? If a man's philosophy does not let him protect his people, his home, and his family… what good can it do for the world?
 * Apprentice: Peace be with you.

Trivia

 * The last part of his name (cel Trădat) means "the Betrayed one" in Romanian, which fits the circumstances of his defection from the Assassin Order, based on his Wallachian heritage.
 * If Ezio assassinates Vali before the Apprentice, the cutscene still shows the Apprentice saying his line.
