History WMG / ThroughTheEyesOfAnotherPony

* Celestia is going to give the Codex back to David in return for bringing back Firewall, because Luna is heartbroken without him. David does so, but uses this as a pact on Celestia and/or leaves out Firewall's memory (given the ending of chapter 14) so he won't prove to be much of a problem.

* The whole thing is a XanatosGambit by the previous human to drop into Equestria.

* David is in fact a future alternate-universe version of Notch, who having acquired the wealth of entire galaxies, invested in the development of the Codex, leading to the penultimate form of Minecraft that is now running a replica map of Equestria.

* Everyone is Jesus in purgatory

* The story ends with Firewall at the very least in a state of contact with both Earth and Equestria. His memoirs are clearly written with the intent of being told to other bronies, but he also occassionally retracts statements 'at the insistence of a certain annoying pony...'

* This is not a fanfic, it actually happened to the Author, hence the higher quality and great detail.

* Firewall is telling Part One of the story to someone on Earth. His references and asides might be an indication of this.

* Firewall's body is part of the Nightmare; it was created to be the permanent vessel for the Nightmare. However, it didn't merge with it, but kept a connection. That's why it was able to bring Firewall into Equestria as a pony as opposed to a human. Also, what do you call a horse with flame powers and hair? A nightmare.

** Also, Twilight Sparkle is clearly Luke Skywalker. I mean, why else would they play something that sounds an awful lot tike the music at the end of A New Hope when publicly recognizing her heroism, and she's already the most powerful thing in the known universe short of the local physical gods and is apprenticed to one of them. Therefore, the MLP:FiM 'verse also includes Star Wars.

* Firewall gets his phone "reformed" back sometime later. Then Celestia copies and absorbs it as well... including all the "Trollestia" and "Molestia" content. Which gives her bad ideas.

* The entire story can be reconciled with series cannon by taking place in the Equestrian timeline entirely after all of the events that have occurred and will ever occur through to the inevitable future end of the animated series; however, relative to Earth time, all such events have already occurred before the initial airing of the series' first season, thus Firewall would only have knowledge of the events that aired in the first season and would only learn of events from later seasons through some form of exposition from the other characters.

* Infecting Celestia with the Nightmare was always part of Luna's plan to bring about eternal night, since now she can legitimately hold the sun down and say it is for everypony's own safety.
