When he was a small cherub, Dandelion was sold to a wealthy woman who saw him as nothing but an ornament for the luxurious parties she hosted at her manor.
One day, a fire breaks out at one of those parties. She got rid of everything that got burnt and replaced it. Dandelion included.
However, a vampire who happened to be at that party, decides to keep him and perhaps use him as his personal juicebox.
