Jeremiah grew up in a godless environment as from a young age he was abandoned by his parents and the childrens home he lived in didn't focus much on religion, he was never baptized and he never did his first communion. He was never really a believer, but this changed however as one day he met a girl by the name of Mia Busch who introduced him to the world of Christianity.
Jeremiah was skeptical but Mia convinced him to join a religious group she had been a part of for some time, before he joined this group Jeremiah was baptized and recieved the Eucharist for the first time. The group spent countless hours in service of those who needed help which led Jeremiah to do the same, he eventually quit school in order to spend more time traveling the world helping others.
His group didn't want to head into war torn countries so Jeremiah had to find a new group, after months of looking he found a "Aetherious society" that was willing to travel to these countries, Jeremiah joined them as they made promises that they would not keep. This landed him in Takistan, a place torn by a recent war which had turned into a civil war between Insurgent cells and Takistani Armed Forces aided by NATO troops.
Jeremiah spent many hours a day talking to James Jouret, the leader of the group. Jeremiah eventually saw James as his father and seeing as how he never had one, this was the relation he had been looking for all his life. Blinded by his love for James, Jeremiah started adopting the extremist ideals that the group believed in and became a true member of the cult after his initiation, the cult believed strongly in the old testament but with some modifications made by their leader. Jeremiah started going down a path of hate and anger as they made him believe that in order for the new world to be established, the old one must be destroyed.
After aiding the Takistan insurgents in their fight against NATO troops, James and his cult moved to South Zagoria to aid the chaos that ruled over the land due to civil war.
