Mine is just there was an Age of Decay

@northern haste  
That’s kind of what I said.
 
 
@Ack_Attack  
Yes, the “Journal of the two sisters” also implied it. It said that the three tribes (unicorn, earth pony and pegasi) wanted an alicorn ruler because they all knew that alicorns bring harmony & unite the best aspects of the three tribes.  
HOWEVER, how can two foals without cutie marks already brought harmony? The only answer is, that there are/have been more alicorns.  
Flurry Heart could be a special case. The spell that caused Cadence to become an alicorn might have the side effect that her children will also become alicorns. Same for Twilight
 
My headcanon is that alicorns are similar to the “Slayer” or “Avatar”; there are x alicorns in each generation. As soon as one dies (for example by giving up their immortality), a new one will be born. That explains why Equestria only has 2 know alicorns.  
To help the real alicorns, those who helped Equestria more than anyone else, are ascended to fake alicorns. Twilight by saving Equestria a few times, bringing Luna back, saving the Crystal Empire and solving Starswirl’s spell and Cadence by reforming a villain who controlled the second crystal heart (yes, it was a necklace and had limited power, but it still was part of the real crystal heart). Who knows how many ponies had been ascended to alicorns while Celestia was alone for 1000 years?  
Those fake alicorns are bigger and stronger than other ponies but not immortal.
 
However, in my headcanon, there are 3 alicorns because only then we have true harmony: “Light, Dark, Twilight”, “Good, Evil, Neutral”, “Sun, Moon, Planet”, “Heaven, Hell, Mortal Realm”  
So if there is a big decision to make, it takes three to decide and to avoid a draw. Once again, this is my headcanon so there is no point in arguing^^

@LaszlVFX  
Which also implies that there might have been born-alicorns before Celestia’s and Luna’s own births.

@northern haste  
Just because Celestia said “The birth of an alicorn is not something Equestria has ever seen” that doesn’t mean it’s out of question that Celestia and Luna are born alicorns. They were born before Equestria was founded.

@LaszlVFX  
The show only said that Equestria never saw a born alicorn but we’ve known since season 2 that Equestria is not the planet

@Iron_Shield  
Celestia and Luna are born alicorns. Lauren Faust has confirmed it once.

@Iron_Shield  
nope, Celestia and Luna were born alicorns. read “Journal of the two sisters”, a offical and canon book;-)
 
I don’t know where people got that wrong information about Celestia and Luna

@Tirek  
wrong too,  
Celestia and Luna were born as unicorns, only Flurry was born as alicorn.

false  
Celestia, Luna and Flurry are born alicorns

Evidently false.
