Dear Dragon

The Union was a political declaration of cooperation. Humans, mages, fairies, and many other magical and non-magical species worked together under the same king to maximize efficiency. The kingdom was thriving in comparison to its neighbours.
Yet, not every species saw their quality of life improve. One species saw very little of the Union, as they vanished shortly after joining.
Most people didn't think much of dragons' disappearance, supposing dragons up and left. Itazu was not one of those people, see, that would mean they left her behind. And from what little she remembered of her mother, and the stories her father told, it seemed unlikely.
Itazu hid her heritage from the world around her. She did as her father recommended, she didn't transform or use her strength. She worked at a busy bookstore and buried her curiosity deep down.
Until a letter arrived addressed 'Dear Dragon', promising answers. Itazu had common sense, but not enough of it to outweigh the now growing tree of curiosity. She followed the instructions in the letter, onto a train heading to an unknown location.
Had she known she wouldn't be back by Monday, she would have left a note for her father, but it was too late for that now.
