Hello everyone,

I'm posting this thread regarding a crossover idea I won't be able to write due time, but I'll put it on adoption to anyone who is interested.

The fic sets in the aftermath of "A Canterlot Wedding" while everypony celebrates with joy, well save for Princess Celestia who feels remorseful and upset with herself for the earlier events - mostly her position towards Twilight Sparkle - and what could have happened if Queen Chrysalis and the Changellings suceeded in their invasion. Seeking solitute for the moment, Celestia have a conversation with a being from another universe in search for advices and how to let the grief of almost losing everything for a mistake out of her.

And that being is... Optimus Prime.

Very likely already done.

Really? Can you please send me the link to the fic?

I said very likely.

Given that ACW has enough FixFics to fill the library of congress by this point, this idea is out there somewhere already.
