Wings of the Guardian - Immortal Guardian, #1

Enkidu awakes from his stone prison, a daimon in the form of a chimaeric creature, part lion, part falcon. Nanaia, a beautiful priestess with golden hair is the first thing he sees upon awakening. She gives him his purpose and reveals his curse: to be an eternal guardian for those of the royal blood. She baptizes him Farvardin. Farvardin, who was Enkidu who was once.something more ancient and terrible, rails at his fate, and longs for the life he once had, the friendship of a great king and the love of his wife.
But it doesn't take him long to realize how much he now wants to stay alive. He immerses himself into the political intrigues of a Babylon ruled by a young but wildly successful Macedonian conqueror named Alexander, the man he is charged to protect. His failure to keep the great king of this age alive will cost him more than just his life. The curse of the immortal guardian guarantees it. Wings of the Guardian is a short story in the Immortal Guardian series
