She is Osane's knight and protector. She gets alone with her charge well. She has no issues with socializing, save with nobles who take issue with a commoner who freely speaks her mind. Despite the domain's mixture of races, Rosalia is descended only from wood elves. Her family has been known to have occasional druids born into it. She carries a bow and a hunting knife. Her beads from Osane are braided into hair ties.

Rosalia is a cheerful and helpful person. She enjoys her servitude to the royal family. She backs princess Osane entirely. The two of them have no interpersonal issues. She wishes she was able to experience the presence of aether in the same way those with ties to aether and the divine do.

She is relatively tall and lithe. She stands at about 5'6 (166 cm) and 150 lbs (68 kg). Rosalia's voice would be soft/quiet. But, medium to high.
