Arbaaz Mir was born in Kashmir in northwestern India during the early 19th century to a Muslim family. His home region was conquered by Maharaja Ranjit Singh of the Sikh Empire in 1819, leading to the death of numerous Muslims in Kashmir, including some of Arbaaz’s kin. This led Arbaaz to grow up with a resentment towards Singh, considering him a cold-blooded killer.
His revenge led him to go after Singh only to be thwarted by the Assassins. He was taken from India and handed over to Dastan and Altaïr. Both saw potential in him, but also his anger. They worked to train him, and in time they watched him grow into a steady Assassin.
Dastan escorted him back to India, hearing rumors about his old enemy, the Hassassin. When they arrived he discovered that Templars were using the British Government to influence the Maharaja so they could control the land and wealth.
Arbaaz had to face his own emotions when he came face to face with Singh.
He realized they were trying to poison the Maharaja, and knocked the tea out of his hand, instead of watching him die – but it was already too late. The Templar escaped but Arbaaz stayed with the Singh, and told him he forgave him.
Ranjit smiled and died peacefully.
Arbaaz barely had time to react when the Templar returned. He defected the blow, but ended up with a mortal wound before he gave the killing blow.
Dastan found him and gave him a new chance.
