That Hippolyta is on the cover of TotA #2 means that she is not the one who dies at the beginning of the saga.
Cloonrad also said that they are interested in developing what Hippolyta learned in the world of man.
I don't remember why or what I read that the idea occurred to me that someone would die at the beginning of the saga (Phillipus? Clio? Hellene? Faruka?) and someone more important would die at the end (Cassie? Hippolyta? Donna?)
