Originally hailing from New Canaan, Daniel used to help the Sorrows with various medical problems and general difficulties, but was sent to Zion as a missionary by Bishop Mordecai to convert those who were willing to follow in the path of God. After the destruction of New Canaan, caring for the tribals became the focus of Daniel's attention. He feels that the Sorrows would not have been subject to the wrath of the White Legs in the first place were it not for the interference of the Mormons.
Daniel claims that he has dragged other tribes (such as the Tar Walkers and Crazy Horns) into the war against the White Legs, and this has a profound impact on Daniel, as he does not want to lose the Sorrows. Having witnessed the tribes suffering at the hands of slavers, raiders and NCR prospectors he has dedicated himself to protecting them and tending to their needs. He intends to accomplish this by helping the Sorrows evacuate Zion to safety out of a desire to both remove them from harm's way and prevent them from falling into militancy to defeat the White Legs. He fears war with the White Legs would change the Sorrows from what he views as a life of simple innocence into a more warlike culture - the same way of thinking that led the world to ruin, led Joshua Graham to become the Malpais Legate and created men like Salt-Upon-Wounds.
In the shadow of Daniel's death, those Sorrows who survived the assault on Zion Valley mourned his loss, as was their custom. Word of Daniel's passing reached the New Canaanites several weeks later. They prayed that their brother would be well-received by their Lord.
After leading the Sorrows from their home in Zion to safety in Grand Staircase, Daniel continued to wonder if he'd made the right choice. He spent his life evangelizing the beliefs of his people to a new generation of young men and women, as his ancestors had for centuries before him. He was happy with his family, but for the rest of his life there were nights when he awoke with sadness to find he had been dreaming of Zion.
For years after the defeat of the White Legs, Daniel did his best to minister to the Sorrows' spiritual needs. Try as he might, he could not hold back the tribe's increasing militancy and reverence of Joshua Graham. Demoralized, he returned to his family at Dead Horse Point. His failures haunted him for the rest of his days.
