Rhine Renard, also known as the Witch, is a character featured in Hymns to the Sun. She is the twin sister of Rowan Renard.
First appearing as a bystander in a crowd of onlookers listening to the prophet Vor, she eventually stepped up to challenge him. Specifically she cited his attempts to revive the "barbaric" old laws, which had fallen out of favor with much of the populace and had been gradually rolled back by previous rulers. Vor correctly guessed that Rhine had personal reasons for attacking him, and she admitted that Rowan was seeking Vor out. She pleaded with him to turn her brother away, but he refused.
Rhine believed that Rowan was pointlessly rebelling against his nature, and that his attempts to find Vor would only lead to more suffering. She repeatedly tried to deter him, even resorting to witchcraft in order to prevent his reaching the prophet.
In a final effort to stop Rowan, she visited the Cult herself, outfitted in various "magical" items and charms. Her brother begged her to leave peacefully, but she refused, threatening the other cultists with demonic retribution for the death of Lilia Merriman, who had been murdered by the cultist Daniel.
Following through on her threats, she reported to King Tristan Stirling that Vor was hiding a murderer among his disciples, protecting him from the law. This led to Vor's arrest, trial, and eventual execution. Daniel, on the other hand, was entirely ignored; the trial was a mock one intended merely to rid the king of a threat to his power, not to deliver justice.
