Constella is the spirit of wayfinding, embodying the method of using stars to traverse the land and sea. Constella is very self righteous, believing she is above normal folk(non spirits) and a being of true beauty. She thinks that those who travel and move around a lot owe her thanks for their ability to do so. This has led to a sort of mothering complex to normal folk, believing they need her help to successfully navigate despite their many inventions that help them do so. She can get flustered about expeditions that find good fortune without her input.

Constella has a shrine that travelers occasionally go to and make offerings. The most common of these are sailors praying for safe and easy travels. While the offerings vary, the most common ones are money, gems, valuables, and bouquets of flowers. Her favorite offerings are trinkets made of glass and mirrors, enjoying seeing how they magnify or reflect images and light.

Like all other spirits Constella has a body split between the physical and magical planes. While she can change it, Constella retains her physical form to a horse. She does this as she believes horses to be beings of beauty. The only exception to this is when she is doing her spirit duties such as guiding a lost sailor, helping an adventurer find a safe path, or appearing at her shrine. During these she will make her horse form appear corporeal as a mist with stars twinkling in it. This has led to few knowing what her physical form looks like, allowing her to mill about in the day to day incognito.
