Shiva Salman Khan, also known as Shiwan Khan, was born in Kabul, Afghanistan, on May the 21st 1883. He was the youngest of about six children and his very greedy parents abandoned him for the street, because they're awful people themselves and they thought Shiva was SHIT. As a result, he became a somewhat justified criminal hellbent on the world.
Even then, his master is a completely remorseless monster, named Erse Nadru, who had frequently sent him to dangerous missions, which means he's pretty much one of her underpaid workers.
