Saint is a yule cat and River's pet. She has purple, white, and blue fur, green eyes, and a white stripe down her back.

She is a kind, loving cat who cares deeply for her master and the others on her team, as shown by her constant worry for Aasira while she grieves for Celeste. Nevertheless, she loves to have fun, playfighting and roughhousing. She does her hardest to give her family the best. She is also very sweet to Riv, always protecting him.

Saint can generate fog and can even breathe it.

She can also walk on water.
