Why time travelers haven't fixed the 40K universe.

I was there the day Horus won the war...

This is one of my personal favourite theories about time travel. You'd struggle to actually change anything, because every influential person in the world had a deputy. So someone else simply fills those boots and everything keeps rolling. If you try to change things without killing people, you get ignored as much as any other detractors, moreso because of your crazy claim that you're from the future.

Hell, the Chaos Gods might occasionally do this just for the sheer amusement of watch someone try and fail to even have an impact.

There is one explicit mention that I can think of of time travel in the conventional sci-fi sense, and I think its in a black library battles of the space marines book where they board a space hulk for archeotech, and it does give one reason in there.

I was there the day Horus won the war...

Is that Oll Persson? Or a John Grammaticus quote?

[Psychosplodge]

Yes.

Though wasn't the original I was there the day Horus slew the Emperor?

[Houghten]

Yes, and it's neither of the Perpetuals, it's Garviel Loken. See Horus Rising, first chapter.

[Psychosplodge]

But............. Loken WASN'T there to see Horus slay the Emp - Loken was busy being a madman on Itssvan, and then got wrapped up in the fledgling Grey Knights.

[Psychosplodge]

Who's to say the fledgling grey knights weren't at the final battle?

I'd tell you more, but it'd be spoilery. Go read Horus Rising.
