This operates under the assumption that they were thrown into the future around the time Sunset was banished. Which, by the way, they would have already been almost in “the future” just by waiting at that point.

Also, what plot hole? If anything, this creates one, as Starswirl’s banishing just taking RR into account never said anything about throwing them into the future.

Enough time for them to attempt collecting magic, failing to do so, and realizing that “the energy in this world is different”.
 
Could be as little as a few days for all we know.

So what they are trying to say that they were from 1000 years ago but they are not that old? Interesting.

On a side note, I wish they had been dropped in medieval times. More fun stories to tell!

How long ago from Rainbow Rocks did they land in the human world? A week? A month? A year?

Sending them to the future has always been my head canon since…well, that’s honestly the only logical explanation for why they still look so young.

@Masem  
They feed on negative energy and discord. This is their path to immorality. Anderson filled a “plothole” that didn’t exist.
 
@soundtea  
A much, much, MUCH better “epilogue” type thing would have been a montage of them causing problems over 1000 years of human history. This was just stupid.

@Masem  
Why wouldn’t they be immortal?

At this point in time the Sirens aren’t aware that extracting magic from humans wont restore their powers, so Rainbow Rocks shows them after they realize that fact. (I’m tired of fast food!).
 
Considering that wormholes are tunnels in space-time, it’s perfectly understandable that the timelines might not sync-up across dimensions. Someone already confirmed (was it Meghan or one of the directors maybe?) that the time flows at different speeds in each world.

@Masem  
Remember how they feed on energy? It doesnt take much to think that’s how they stayed alive for 1k years.

@Masem  
That’s a real weak as hell explanation. And going by appearences, that is the exact mirror. No way forcing them through would screw up the “when” by a factor that lands them conveniently right when EQG1 and RR take place.
 
And it kills a much better backstory, with them inciting conflicts for energy over the 1k years they’ve been stuck there.

Adagio is seriously taking this in stride.

@martianmister  
People have been asking how the sirens have survived for 1000 years in EQG world, since that’s when SS would have banished them.
 
Instead, this replaces that (having the mirror warp them forward in time) with a different, but more easily-handed waved plot hole of how the heck did the mirror do that and not for Twilight the first time?

The more they try to explain, the more convoluted and contrived the entire thing is.

@soundtea  
He might have had to force the mirror to open which altered the way it behaved compared to the “every 30 moons” point. Also consider there might be multiple magic mirrors (though the comic suggests this is “the” one to EQG world).

@soundtea  
Apparently when Sunset was exiled, the Dazzlings skipped forward to 21st century Earth for some reason.
 
You know, the place that the Dazzlings would have been for over 1000 years already and have gotten to that point just by waiting?

And here’s the supposed plot hole of RR filled
 
What plot hole?

@soundtea  
Actually, add Sunset to that list too.
 
Ted, keep your shit together.

That…doesn’t make sense.

Wait, then how in the hell did the mirror not change at all when (but somehow where) to send people when Twilight used it?

But….why?
 
-should be a thing I should stop asking by now.
