The Accidental Invasion

by computerneek
When a magical accident occurs, there's a small chance it'll invite an invasion. This one did.

Even the smallest magical accidents, as anyone in the Accidental Magic Reversal Squad can tell you, can have significant and far-reaching effects.

Especially if it wasn't Accidental Magic at all, but deliberate magic that was doing something that wasn't intended at all. Like, for example, the very trustworthy ancient magic of Hogwarts suddenly choosing to invite about fifty times as many students in one year as it usually does.

Naturally, when these small yet significant magical accidents happen, there is almost always someone that doesn't want it corrected for some reason or another. In this case, that someone is in a position of power, so it doesn't get corrected.

And over ten of thousand new students are officially admitted to Hogwarts in a single year. After all, these new students bring with them stories of things thought and even known to be completely impossible, in some cases, and the complete conviction that they are possible where they come from, wherever that is.

Naturally, Dumbledore expected that someone would make them possible. What he did not expect was the who and the how.

A rewrite and reimagining of the once-popular On the Implications of Parallel Worlds, which was itself a rewrite and reimagining of The Gate. This time around, it should be a little easier to avoid deadlocking the plot.

Written with the editing and proofreading assistance of Skittlebug (Former), Gerandakis, Rose, and Raven, and I can't be bothered to find links to their profiles right now- or even their full profile names...

As always, tags may be updated as the story progresses.

Will update weekly on Tuesdays, following the death of On the Implications of Parallel Worlds, or when ready on Patreon.

Cancellation planned for around chapter 85.

It could be argued that the phrase “based on a true story” applies to this story.
