Kyros rarely talks about his past, what is known is that was an orphan on the streets of a Hive World Maxilos before the Star Reapers recruited him. Fending for himself in the dark alleyways of the Hive City Maxil Secondus, Kyros became a cunning survivor and ruthless killer. His aptitude for violence would grant Kyros entrance into one of the largest gangs, known as the Sixth Sons. Eventually his gang activities as a petty murderer paved his way into the neglected and violent Pit, a prison located in the deepest sub-terrain location of the planet. Managed by cruel jailers and heavily armed guards, Kyros was set to rot away there for the rest of his days.
