| ||For other characters in the Fallout universe named Martin, see Martin.|
According to DiMA's memories and accounts made by the Children of Atom themselves, Confessor Martin was the former leader of the Children of Atom when they first came to Far Harbor after receiving visions from the Woman in the Mist.
After some time, they were kicked out of Far Harbor due to their belief and DiMA, out of pity, gave them a place to call their own. Residing within a defunct nuclear submarine base known as the Nucleus Martin eventually became close friends with DiMA and he and his followers were the first to accept the synths.
Yet after one of his preachers was executed by the harbormen, Martin began to grow more hostile to not just Far Harbor, but also to DiMA after he gave them fog condensers. Martin tried to persuade DiMA that they should both try to convince the harbormen to leave the Island, both for the harbormen's safety and to satisfy the Children. But DiMA wouldn't be swayed. Eventually, the two split apart and DiMA hasn't heard from him since. He later abandoned his congregation, and in his absence, Tektus rose to become the new High Confessor and radicalized the Children further.
