I have seen this 'riddle' a lot, and as far as I can tell its not asking anything.
Anyways I know there are 3 movies in it, and thats all I can gather really...
Avatar can mean picture, and picture can mean movie... I have lots of other blable I got from this, but can't get anywhere with it.
Ill keep trying, good luck to both of us.
Edit: You know that eschaton is the end of the world right?
