Sisir is the 4th child of King Lucifer I of Hell and an angel noblewoman. They were born in secret after Lord Baphomet staged a coup and took the throne. Their mother was hunted by Baphomet's soldiers while they were a baby, and she made the hard decision to send Sisir to Hell to be raised by one of her close friends. 

Private Essex Haynes raised Sisir by himself as a single father. They grew up loved and well taken care of, despite the circumstances of their birth. They were told that their parents were an unknown angel and demon couple who were killed by Baphomet's forces. Haynes kept their identity a secret from everyone, but taught them to fight from a young age in case they were threatened. 

Sisir spent their days flying through Hell's chasms and exploring the vast expanse of hell's scenery. Despite Haynes warnings (a powerful nephilim is hard to tell no), they began to attend demon parties and meet many friends and foes along the way. 

The most intriguing creature they met was Raziel. Haynes was one of Hell's researcher's, and he was tasked with studying one of their enemy's weapons: an angelic soldier taken prisoner by Baphomet's men. Raziel was not a normal angel. He was created in a lab to be a super soldier-an angel stronger than any other. Unfortunately, their efforts created something less angelic... 

Sisir was quickly taken by their father's research subject. They talked to him through the bars of his cell, bringing him food and bandaging his wounds. They began a secret romance, the nephilim promising to free him as soon as they could... and Raziel swearing to destroy anyone who tried to hurt Sisir. They talked often of a life all their own, free to fly together with no one to keep them chained down. 

However... one day Sisir would discover who they truly are... and the family they never knew.
