Callisto

Description
Callisto is a mysterious character who seems to wander from place to place with her mystical tent, making observations about all the characters and enemies she comes across for the player to read. She also has a knack for helpful magic spells, such as healing, transformation, or friendly chat (-15 mana).

Callisto is the main ally in Beth and Edward's adventure, as her knowledge and abilities were essential in paving the way towards Belladonna's world.

Callisto is unsure of her true origin or purpose, as she, along with Cordelia, seemed to just appear one day with no prior memories or life. This is troubling to Callisto, and most of her actions are based around a desire to know more about herself.

Personality
Callisto is very friendly, although a bit cryptic at times. Much to the dismay of Cordelia, she never stops travelling around the world trying to find out just what she is. She can come across as a bit distant, avoiding emotional attachment to the many things she may never see again. Perhaps when her life's mystery is solved, she can find real happiness.

Beth and Edward
After hearing of their sister being stolen by Belladonna, she decided to assist the siblings in recovering her. She gives them valuable advice and information, as well as a few magical powers. Overall, however, her treatment of them is that of a stoic teacher, and not so much a friend. After the adventure is concluded, however, they have all grown a great respect for one another, and Callisto has appeared at many of Ryland's barbeques.

Cordelia
Though they are unsure if they are directly related by blood, Callisto and Cordelia treat each other as sisters. Having nobody else in the world they travel together. Cordelia cares far less about their origin, however, and just wishes they could settle down in one spot and live like normal people. This causes her to often wander off and attempt to be independent, with often disappointing results. Although this is very hard and worrisome on Callisto, Cordelia always seems to come back unharmed at some point.

Belladonna
Callisto hates Belladonna with all of her being. There seems to be some feud or vendetta between the two, although this is unclear. Belladonna severely outmatches Callisto with her destructive magic and army of creatures, so they don't see each other much.
