The Tale of Sparrow Scales the Pony-dragon

Before Sparrow was born her mother was a intelligent explorer pony named Feather Truth who came across a dragon cave and made friends with a dragon named Leir who loved her and didn't tell her until a pony named Ink Map came along and she took a liking to him. At night Leir told him to leave his cave immediately, so after Ink Map left he confessed his love to her and she accepted him and they soon had a daughter.
