The Dragon Emissary

Janus isn't your typical teen colonist; he's close to becoming his people's ruling Emperor, until he receives news of the arrival of a Dragon Emissary. Janus challenges the opposition of the Senate, just to meet the person that had helped his deceased father Maxillus, stop the Dragon war. After befriending the runt Emissary Dragon Amakhu, Janus learns that the emissary has brought his daughter Naima along.
Later that evening, at Janus' estate, two amateur pyroalchemysts kidnap Naima and almost burned down the estate. Janus learns from his closest adviser that her kidnappers were a fringe group supposedly dissolved during the Dragon War by his father. From then on, Janus starts to learn of his family's sordid past and begins to worry about his own fate. After rescuing Naima back, Janus discovers a bigger threat developing overseas.
But first, he must enlist a group of loyalists and misfits to aid him on his journey across the ocean-to the Dragon Realm.
