Sequel Works which add Important Lore Rules which Never Appeared in the Original

Horcruxes don’t rate a mention until Half Blood Prince.

It’s been about 20 years since I watched TNG, so my memory could be faulty. I don’t remember the Enterprise-D ever exceeding warp 10, but didn’t the Borg cube go faster than that in one of the TNG episodes?

If I remember correctly, no. Although they were capable of a sustained 9.8 or 9.9, which meant the Enterprise was not able to outrun them.

The Enterprise-D went faster than Warp 10 in the season-one episode “Where No One Has Gone Before”, when The Traveler ends up taking them to the far reaches of the universe.

It also went to Warp 13 in the anti-time future in the series finale, but presumably the warp scale had changed again.

The dreadful Voyager episode “Threshold” had Janeway and Paris go exactly Warp 10 in a shuttle, ending up occupying all points in the universe simultaneously. It mutated them and they turned into slugs and procreated with one another.

In Star Trek: Picard, in 2401, the Titan-A was able to go as high as Warp 9.99 on the “TNG” scale. That is much, much faster than the Enterprise-D’s Warp 9.9 in “Encounter at Farpoint”.

As far as the Borg go, they had access to a series of transwarp conduits that allowed them to go faster than Warp 9.9, but they existed outside normal space-time.

It’s been a while since I read them, but I’m pretty sure in the book it’s for all wands. They simplified it to just the elder wand in the movies.

I disagree with this. JKR had the entire 7 book arc planned out from the start. The fact that V preserved his life beyond death was part of the story from book 1. V’s diary appeared in book 2 and was a horcrux. HBP just gives details on something that was central from the start.

Hmm…I was thinking of the book. From my memory it was the Elder Wand and went like this. Draco defeated Dumbledore in Book 6. Harry defeated Draco in Book 7.

Tom Riddle thought Snape was the Elder Wand master because he killed Dumbledore, which he kind of did and didn’t.

Harry was the master because Draco, not really realizing it, had been the Elder Wand master.

The OP asks for important lore rules that don’t appear until later, and that’s true of horcruxi, even if she had them in mind.

I think the difference is that many of these examples came out of no where, but JKR laid the groundwork for the horcurxi even if she didn’t spell out the details.

I do agree. The details were though of in Book 6, but the basic idea was there and Horcruxes put a name and detail on what had happened with:

Tom Riddle not dying when his Avada Kadavra spell hit him

The diary having part of him in it.

The Philosopher Stone being able to restore him to full life.

In the first Halloween film, Laurie Strode (the Jamie Lee Curtis character) becomes Michael Myers’s target when she drops off the key at the abandoned Myers house. Unknown to her, Michael is inside the house, sees her, and becomes fixated on her. It’s entirely random bad luck that she came into his sights.

The sequel, Halloween II, introduces the notion that Laurie is actually Michael’s younger sister, put up for adoption after the death of their parents. Despite coming out of nowhere (and destroying the terrific “horror comes upon you with utter uncaring randomness” idea that gives the first film much of its power), Michael’s sibling relationship with Laurie becomes an important plot point for the remainder of the series.

In the first Pirates of the Caribbean movie Jack’s compass is specifically for locating the Isla de la Muerta. In the sequels it’s revealed that actually it points to whatever the owner wants most.

Personally I think warp 21 is more efficient then “Warp 9.86!! Warp 9.90!”

Also the warp 10 is infinite speed never made a bit of sense. And if you were ‘everywhere in the universe at once’, you’d destroy the universe. “Would require infinite power” makes a lot more sense.

This spaceship goes to 11.

In Seanan McGuire’s Ghost Roads series, it’s an important plot point in the first and second books that the main villain can’t leave the United States, for magical reasons. He can’t.

Then at the end of the second book, he does. (Admittedly, I haven’t read Book 3 so maybe it’s explained, but it still feels like a cheat.)

Does that mean it’s faster? Is it any faster?

Why don’t you make ten a little faster? Make that the top number and make that a little faster?

Because this one goes to 11.

In The Matrix, long ago someone called The One freed the first people from the simulated world and led them to Zion, and then prophesied another One would someday come to finish the job. In The Matrix Reloaded, you find out this sequence has repeated many times over, and The One’s real job is to perpetuate this cycle by helping to build a new iteration of The Matrix.

I’m sure the Wachowskis had this in mind when they first set the story down but the first movie never hinted that The One was anything other than the promised savior of humanity.

Another egregious part of retroactive lore in the series is the book containing the pirate code. It was previously a big part of the plot that they were “more like guidelines”, but then in a sequel, they break out a big book with the pirate code to look up the exact wording of a rule.

Speaking of Star Trek: Data can’t use contractions - a fact that was made up for “Datalore” halfway through season 1; except of course until that point he had used contractions from time to time ( and occasionally after that too)
