This is where Calista and her older siblings were born. There were four of them, her older brother, Micheal (usually called Mickey), the oldest of the sisters Adrienne, and the middle sister Cyrille. When they were all younger, the family would have what they called 'family time' almost every night. When it was family time, and together the family would do all sorts of different things. The activity that Calista enjoyed most was when they baked sweets; she loved creating all sorts of pastries her mother learned to make in Lumiose, decorating them with frosting and other goodies (which of course got all over the floor), and then seeing and eating the pretty final product (with mother's touch ups, of course). She grew to really like it, and started doing it by herself when she got older.
Calista's life in Lavender Town was rather slow and uneventful until she turned six years old. She was out playing with her friends when it started getting late. Instead of turning to go back home, however, the kids got an idea; the Ghost-types always hung out in the Pokemon Tower, and none of them have ever seen it before. Their parents had always warned them not to go in there by themselves, especially at night, but they were big kids now, they weren't afraid of no ghosts! So, Calista and her friends wandered inside, and didn't find much until they started moving up and up on the floors. Things were getting darker, spookier...was that someone leaning over your shoulder? Before Calista knew it there were shrieks and her friends were running like crazy in all different directions. Her mind couldn't register why at first, but when it did, it hit her hard. Some of the Ghost-types who resided in the tower had appeared, and by this time she was by herself. The ghosts didn't want to let her go so easily...they decided to have a bit of fun with her first, scaring the at the time Sentret girl, making her scream and cry and run until she was lost in the tower. If her older brother Mickey hadn't come for her, she wouldn't have been crying by herself in there all night.
After that incident Calista's views about Lavender Town and its inhabitants changed dramatically. She was now terrified of Ghost-type Pokemon, the smallest creaks of her house keeping her up at night. To keep her calm, her brother Mickey wrote a small song for her; he played it for every night, telling her it would keep away the ghosts. The song never got an official name, they had just called it "Calista's Song."
As Calista grew into a teenager, her parents started becoming worried about her. She was a well-rounded, sweet girl sure, but because of that incident and her constant surroundings Calista was getting anxiety; she would get scared more easily, constantly worry at night, she was afraid. Despite her parents wanting to help her get over her fear, Lavender Town was certainly not the place to do it.
In school, Calista had been doing great. She was a diligent student, always handing in her work on time, and putting away some time to study. This gave her parents an idea. They started looking at other schools, one away from home Calista could transfer to. After many different options they came across the Armonia Institute; a school where special Pokemon would learn about balance, courage, and harmony. Reading about it more, they decided it was the perfect place.
They told Calista all about the school, and almost immediately she was captivated by it. The school sounded amazing, a prestigious, beautiful school, she could perhaps take baking classes...and, even though she kept the reason to herself, it was away from Lavender Town and all the ghosts. Happily, Calista agreed to sign out an application to attend, hoping and praying to get accepted.
