In a place and time unknown to us, man has come to an era where they discovered the mechanics of flying.
Some aeronauts are successful in their attempts to fly, using the newly found knowledge combined with their technical skills.
Others are dreaming about pushing boundaries and "go where no-one has gone before".
And then there are those who will have to take their plans back to the drawing table.
Soon, this new technological evolution draws the attention of the Gods, and they send their first Angels to go and investigate what is going on.
