This discussion is in regards to the mysteries surrounding Eden's past and the clues that have been whispered in the books for those who can catch them. While it's no secret at this point that not everything is as it seems or thought to be in Eden, there's something else hiding, almost in plain sight, about the world that almost nobody seems to see or remember. Some examples are:
-The very first opening citation in the series
-The creation of the Cities of Eden, supposedly by humans themselves
-The Dark Queens arrival in the world and their imprisonment
-The key fragments and materials used in building the ancient cities
-What Sasha almost let slip when speaking to Mika in Act X
There are numerous hints scattered through certain books that point to a bigger truth that's so far remained hidden and forgotten to most of the world. Needless to say at some point something special is going to be revealed and change much of how Eden is viewed, but until then I invite any and all to voice their thoughts and guesses as to what secret lies in wait in Eden's shadow.
