History Literature / TheJournalOfTheTwoSisters

* DugTooDeep: There were tales of a great dragon living in the caves where the crystal heart was found, but no pony has seen it in many years. Clearly this means it is safe to mine away without thought to the consequences!

* {{Retcon}}:
** Luna uses the word "fun" in her diary entries, even though in [[Recap/MyLittlePonyFriendshipIsMagicS2E4LunaEclipsed "Luna Eclipsed"]] she said she had never heard it before.
** Celestia's and Luna's personality traits don't exactly match up to the Elements of Harmony they were seen to hold in [[Recap/MyLittlePonyFriendshipIsMagicS4E2PrincessTwilightSparklePart2 "Princess Twilight Sparkle - Part 2"]].
** In general, one possible reason for inconsistencies between this book and the series, or the fandom's interpretation of Equestrian history, may be that while Amy Keating Rogers is a well-regarded writer for comedy and SliceOfLife episodes, she didn't write any of the adventure and WorldBuilding episodes that the book draws from. [[Recap/MyLittlePonyFriendshipIsMagicS2E1TheReturnOfHarmonyPart1 "The Return]] [[Recap/MyLittlePonyFriendshipIsMagicS2E2TheReturnOfHarmonyPart2 of Harmony"]] and [[Recap/MyLittlePonyFriendshipIsMagicS2E4LunaEclipsed "Luna Eclipsed"]] were written by M.A. Larson, [[Recap/MyLittlePonyFriendshipIsMagicS2E13HearthsWarmingEve "Hearth's Warming Eve"]] by Merriwether Williams, [[Recap/MyLittlePonyFriendshipIsMagicS4E1PrincessTwilightSparklePart1 "Princess]] [[Recap/MyLittlePonyFriendshipIsMagicS4E2PrincessTwilightSparklePart2 Twilight Sparkle"]] by Meghan [=McCarthy=], and [[Recap/MyLittlePonyFriendshipIsMagicS4E3CastleManeia "Castle Mane-ia"]] by Josh Haber.

** Luna's [[InSeriesNickname nickname]] for Celestia is "Celie" (which {{Josse|d}}s the {{fanon}} that it's "Tia".)

* NeverSmileAtACrocodile: Cragadiles show up once again here, albeit in a more positive light, as they help the Princesses set up their castle in the Everfree Forest.

* WorldBuilding: The main function of the book. The first diplomatic contact between Equestria and the Crystal Empire, Griffons, Zebra, Dragons, Manticores and the various internal tribes of Equestria are all depicted in detail.

''The Journal of the Two Sisters: The Official Chronicles of Princesses Celestia and Luna'' is a officially licensed companion book to the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' series written by show writer Amy Keating Rogers, designed to be a {{Defictionalization}} of both the Journal of the Two Sisters (dur) and the diary Twilight Sparkle and her friends were writing throughout Season 4 of the show.

* CerebusRetcon: The events by which Celestia and Luna took up movement of the sun and moon. See PoweredByAForsakenChild below.

** Celestia's and Luna's personality traits (see CompositeCharacter above) don't exactly match up to the Elements of Harmony they were seen to hold in [[Recap/MyLittlePonyFriendshipIsMagicS4E2PrincessTwilightSparklePart2 "Princess Twilight Sparkle - Part 2"]].

* AsYouKnow: Conspicuously averted, for good reason. The diary entries cover a fairly short amount of time, and neither princess goes into great detail about what happened [[VoodooShark before they became rulers of Equestria.]]

* SeinfeldianConversation: The activity with which Pinkie intends for Lollygabbing Day to be celebrated: ponies constantly talking about nothing.

* WhatHappenedToTheMouse: There were other alicorns who raised and educated Celestia and Luna, and other zebras who lived beyond the Everfree Forest, what happened to them?

* VoodooShark: If there were other alicorns who raised and educated Celestia and Luna, and other zebras who lived beyond the Everfree Forest, what happened to them? Why didn't the alicorns do anything to stop the Windigos before the first Hearth's Warming? If unicorns were raising the sun and moon, but alicorns (who could do this much more easily) were around at the same time, where did the sun and moon come from and whose idea was it to have unicorns move them?

* WhatHappenedToTheMouse: What happened to the other alicorns who raised and educated Celestia and Luna, or the other zebras who lived beyond the Everfree Forest?

* CompositeCharacter: In this book, Celestia and Luna take on traits of the Mane Six's personalities -- Celestia has Twilight's bookishness and anxiety about fulfilling what's expected of her, and Applejack's workaholic tendencies (although Twilight has some of them too.) Luna has Fluttershy's kindness and ability to understand animals, Pinkie Pie's enjoyment for playing pranks, and Rarity's love of design and style. From Rainbow Dash, Celestia gets her love of flying fast, while Luna demands things to be ''awesome.''

* BigSisterWorship: [[HeartwarmingMoments Luna clearly adores Celestia, and gushes all over the diary whenever she does something cool.]]

* BigSisterWorship: [[HarsherInHindsight Luna clearly adores Celestia, and gushes all over the diary whenever she does something cool.]]

* DevelopmentGag: One of Pinkie Pie's entries in the journal of friendship is about her efforts to create and popularize a new holiday, "Lollygabbing Day". This is based on an actual episode pitch by Amy Keating Rogers that didn't make the cut.

* {{Retcon}}: Luna uses the word "fun" in her diary entries, even though in [[Recap/MyLittlePonyFriendshipIsMagicS2E4LunaEclipsed "Luna Eclipsed"]] she said she had never heard it before.

* YeOldeButcheredEnglish: The examples of ROYAL CANTERLOT VOICE seen in this book have more grammatical problems than in [[Recap/MyLittlePonyFriendshipIsMagicS2E4LunaEclipsed "Luna Eclipsed"]], e.g. "thou could" instead of "thou couldst", "we art" instead of "we are". Could be [[JustifiedTrope justified]], as this is revealed not to be Luna's native manner of speech but one she learned from the Alicorns, and she could have studied up on its proper rules in the interim.

* InsaneTrollLogic: The griffon ruler reasons that since the Pegasus Empire no longer exists due to being absorbed into Equestria, all its territories are legally up for grabs. Both Princesses point out how little sense this makes.
** [[spoiler:Well not exactly. What he says is that the treaties were between the griffon nation and the Pegasus nation and since the Pegasus nation no longer exists the treaties are now null and void. He's not wrong but the princesses do point out they could just replace the word Pegasus on the old treaties with Equestria and everything would be cool. Gregor says no but it is latter said that he was just irritable because his pastry chef quit on him and he hasn't been getting his sugar rush.]]

** The [[AgelessBirthdayEpisode party for Rainbow Dash]] that was held in [[Recap/MyLittlePonyFriendshipIsMagicS4E12PinkiePride "Pinkie Pride"]] was her "tenth birth-aversary", probably meaning she's been living in Ponyville for ten years. If the candles on the cake in said episode are anything to go by, it would mean that she moved to Ponyville when she was 11.
