This story is a sequel to A Freshly Cut Diamond
Princess Twilight Sparkle discovers a very special flower in a secret cave beneath the library. Upon picking it, she awakens a physically young blue dragon named Kenbroth Gilspotten Heathspike, a dragon who possesses immortality for the purpose of serving whatever Princess picks his magic flower. Not wanting to kick the young dragon out, Twilight allows Heathspike to stay with her and Spike, with the hopes that he and Spike could form a brotherly bond. However, nothing turns out as she had hoped when Spike and Heathspike constantly butt heads, and Heathspike keeps on interfering in Twilight's life with way too many rules and protocols she just doesn't agree with. Can Twilight find a way to resolve this problem without ruining Heathspike's one chance to live life?
