Didn't we knew that text about Shattered Lights already and already guessed that it was just a promo text for the first two Myriad Universes books, hence the six new realities?
Yep, that's the deal. Unfortunately, anything posted on the intertubes breeds like tribbles, so apparently we will never be rid of this confusing six realities reference.
I can tell you my novella, Honor in the Night
, begins with an alternate outcome to "The Trouble with Tribbles" and then follows the ramifications to Klingon-Federation relations over the next hundred years, with appearances by various TOS, TNG, and DS9 characters. It also answers the question, "Why were Nilz Baris's dying words 'Arne Darvin'?"
