Damien was born somewhere in mexico. Not much is known about his background due to his crimes and activities in his young age.
All that is for sure he was part of a Mexican gang called Ángeles de la muerte (Angels of death). His repution and renown growns week by week and soon he was enlisted as one of the leaders of the group. Later he had to flee the country and traveled to Chernorus hoping he could escape the law and live free but as soon he landed in Cherno the police arrested his for suspicious behavior on the airport. he served 2 years in prison when the outbreak happend. Since then he roams the wasteland surviving in the way he sees fit.
