Amara willingly sacrificed herself to the dragons to save her circle of villages. She was her village headman's daughter and the right age, so she had to lead by example. Expecting death since she hit puberty, Amara wasn't ready to look forward to tomorrow. The blue dragons have always found their sacrifices in the village of Ohenimura and yet Daichi was called to a sacrifice of another village. Coming back to Dragonheim proved his people were not ready to accept such a change. Daichi wasn't going to let them dictate to him though and all dragons knew better than to come for another's treasure.
