It represents a third and now final incarnation of Cuāuhtemōc's two previous attempts at such a TL:
The Navatlacas : Heirs to Hernan and Montezuma - After John abandoned his project, Cuāuhtemōc restarted the idea in this newer timeline. Later on, he decided the TL wasn't going completely the way he wanted it to and eventually opted to do this final remake.
Both of these two are now discontinued and replaced by this newer TL. We're leaving them here just for reference and safe-keeping.
The timeline won the "Best Continuing Renaissance and Reformation Period Timeline" category at the 2012 Turtledove Awards.
