D.Gray Man: Appearance of the White Order --Discontinued--

Let's say the Black Order was not the only organization against the Noah. Let's say this "new" order lied waiting in the shadows for the right moment.
Let's say Allen Walker's sister was a member of this mysterious "White Order."
Why has this order hidden in the shadows? Why should it have needed too? Is the White Order as pristine as it appears when it starts making its big moves?
What is the history between these two orders? Why are they disturbingly similar even down to the uniforms they wear? Is there something the White Order doesn't want to be revealed? Or perhaps is it the other way around? Why has the Black Order conducted itself the way it has so far?
As a bookman once said, the story continues.
The question is, is its history recorded correctly?
Who are the bookmen anyway? Why were they trained to do what they do? Who started their mission?
Many more questions still permeate the spectrum between Black and White. Between the blurred line of horrid reality and crude imagination.
