Although not specifically mentioned by name, Reyna was one of the female attendants on Circe's Island. When Annabeth and Percy first arrived (as revealed in The Mark of Athena), she brushed Annabeth's hair and helped with her makeover. She was on Circe's island because her sister Hylla had wanted to protect her from war. Hylla however was one of the attendants that Percy and Annabeth met, who happens to have been the one carrying a clipboard. After Annabeth accidentally freed Blackbeard and his crew of pirates with Hermes' Multivitamins, they captured her and her sister until Reyna and Hylla managed to escape after learning how to fight. She is mentioned once by Percy when the later claims that Carter reminds him of her.

After Leaving Circe's Island
According to Reyna, the pirates destroyed the island and took revenge on Circe. Reyna and Hylla, being daughters of Bellona, learned to use weapons quickly and managed to escape from the island and the pirates after being held captive. Eventually, the two sisters went their separate ways. Hylla joined the Amazons and eventually became the Amazon Queen, while Reyna found Camp Jupiter, and eventually became a Praetor, along with Jason Grace for a time.

As Praetor, new arrivals of the camp are required to meet with her. During this time, Reyna and Jason started to form a close relationship, but Jason soon vanished, forcing Reyna to lead the camp by herself.
