Daniel was the first follower of the prophet Vor. A controversial figure even among the Cult, his sins were the most abhorrent and repulsive of the original nine, and he had the greatest difficulty resisting temptation.
The fact that Vor was hiding him, a fugitive murder, was the official cause given for Vor's execution, although the prophet was actually killed because his growing influence was seen as a threat to the king's power.
Daniel's original name was Warren Zuse. He was the only child of Andrew and Maude Zuse, farmers from the village of Daudel near Io. His mother wanted a daughter, but the couple was unable to have more children.
His madness began to manifest in the empty house, as his parents were too busy to pay much attention to him and didn't see the signs that something was wrong. The young Warren was under pressure to be like his father, becoming a farmer and marrying one of the local village girls.
During a summer fair when he was nineteen, Warren chased a girl wearing a black velvet band in her hair into an open field and strangled her with her braid. This was his first murder, and when he was discovered he was chased out of the village.
He then made his way to the village of Prynne, where he killed another girl, then "ripped out her throat and drank her blood". He couldn't hold down the blood and was again chased out by angry villagers. He managed to visit two more villages, Gylvia and Farthum, killing a girl in each, before word spread and he was forced to live away from civilization or face capture.
Warren fled into the wilderness, where he lived like an animal, naked and alone. The isolation further deteriorated his sanity.
However, a chance encounter with Vor changed his life. He was "cured" of his madness by Vor's presence and refused to leave his side, afraid he would once again return to the abyss. To avoid detection and to start a new life with a new identity, he began going by the name Daniel.
Vor allowed Daniel to accompany him as he preached. Rolfe, a deputy in pursuit of Warren Zuse, found them in Io and arrested Daniel. Vor followed them to the local jail and sat outside Daniel's cell, comforting him during the long night. Rolfe was moved by Vor's words and agreed to free Daniel on the condition he be allowed to join their company. Rolfe remained suspicious of Daniel.
In the city of Zemar, the pregnant former prostitute Sofia Belgrade began to follow Vor. Sofia noticed that Daniel grew nervous around her and later concluded it was because he was afraid she would excite his bloodlust. At Vor's behest he and Rolfe aided in the birth of Sofia's son Vormundus.
As the Cult grew in size, Daniel lived in the cave with the others, but was considered quiet, introverted, and rather strange. His desire to kill had not completely left him and he constantly feared he would cause someone harm.
One evening Daniel, having gone into the woods alone, crossed paths with Lilia, the adopted daughter of Joshua Merriman, who had come to fetch water, fell into the river, and drowned. Beset by his urges, he carried her body into the woods and engaged in necrophilia with it. Horrified at what he had done, he fled deeper into the forest.
Daniel retrieved a hidden dagger belonging to Lord Gavin Zosimus and used it to emasculate himself. He managed to make it back to the river before collapsing from blood loss. The healer Heather Babbitt and the bard Athanasi spotted him lying on the bank, but made no attempt to help him, instead finding the rest of the search party and telling them where he was. Gavin and Kemet carried him to the cave.
Since Heather was unwilling to help him, the physician Nathan Lucassen treated Daniel. While he lay in critical condition, the midnight sun phenomena occurred. Vor alone remained with Daniel in the cave, praying for him.
In the meantime, the other Cult members discussed what to do with him. Various suggestions were made, including sending him to the insane asylums in Zemar, imprisoning him, or simply executing him, but they could not agree on a decision and the debate ended with the arrival of Rowan Renard.
Rowan went in to see Vor, and he witnessed Daniel's confession. Daniel revealed that he had not killed Lilia, but he had defiled her corpse, and the guilt from that led to him castrating himself.
The king's soldiers arrived at the cave without warning. According to the king's orders, Vor was under arrest for harboring a fugitive and obstructing justice. Daniel begged the soldiers to take him instead, but they ignored him.
After learning Vor would be put to death for treason, Daniel visited him in the castle dungeons. Vor gave him a final blessing and sang the death song, which Daniel memorized. Along with the rest of the Cult, he witnessed Vor's beheading.
After the Cult disbanded, Daniel traveled to the city of Hiberia and preached there. He was chased out of the city by the authorities, but managed to evade them for a decade, preaching in the outlying villages and settlements in the surrounding area. His fate is unknown.
