Before telling the tale of the wars in heaven, some things are required learning... Nothing too facy... But you should not judge this as a story written by a christian evangelist in the least sense of the word. this is a work of fiction, based on spiritual themes, it is only a coincidence they use some similar terminology... confused yet? Read the prologue and maybe you wont be :)
now we get to the story itself... This story is about an angel who finds himself in the the middle of the greatest of all struggles... The war in heaven.
The plot thickens, and although we can guess the true nature of certain characters at this point... how the events unfold is where the dramas really lies... and lesson is meant to be learned.
