Bushido: Giant Eagle

The Koroko tell stories to the young hatchlings about the circle of life and of how all is connected, sharing the eternal truth that nothing truly dies but is born again as something else. They say that the great giant eagles that patrol the Ro-Kan, these feathered sentinels ever watchful for the slightest threat, are the reincarnation of great Tengu warriors now watching over the mountain in a different form. Their talons sharp as the strongest steel, appearing from nowhere and disappearing just as fast. No enemy can tell from where these feathered angels will strike next.
