Twin sister of Rhodius Whyatt, born and raised in Tractas.

During her youth, she tried to make a name for herself playing music for the people of Tractas.

At one point, Vulmon Lancynel joined with Tractas for a while when they reached the coastal areas between Kalzendil and Toru. There he met and loved Rhoslia, while her brother did not like him for his obvious surfer attitude, he was too carefree. When Tractas was leaving the coastal area, he offered Rhoslia to come with him, experience the open sea and the underwater marvels. Rhodius was against it. This is where she had to make a choice: Rhodius or Vulmon. She chose Rhodius. But to this day, she still wonders: “What if?”
