Ha!!

Magic, for the lack of a better term, is lazy at times. It can’t just disappear into the aether, go to nothing, and if it’s been stolen from somepony, it wants to return to the owner. Hence, it can be assumed that magic going to neutrality is not the path of least resistance, and magic wants to do any option which is simpler if it exists.
 
Therefore, if ponies shared a cutie mark bond on the level of “almost identical, ala the CMC’s cutie marks,” and one or more of them died, magic would take the next best thing, and funnel into the one(s) left of its own accord. Most ponies would describe such a thing as them being with them in spirit.
 
To bring that official Ponyville Mysteries book series into this, this is how “Auntie Eclipse” became so abnormally powerful for a unicorn, and how she lived so long without explicitly knowing how to do an age spell. She was once bound by a cutie mark bond with other ponies, she was a rather average/weak unicorn, and envied the power of others, but one day, when one of the others died, she discovered she had grown more powerful. Her jealous nature got the better of whatever moral qualms she had, and so she ended up murdering the rest of them so she could grow strong. Her lifespan was drastically increased, though as her body grew frail from age, heavily slowed down as it was, over time, her magic waned somewhat. The False Cutie Marks she gave the others to bind them by, at least some of them were in fact the cutie marks of the ones she murdered/outlived.
 
After all, she declared herself “Eclipse Destiny” when she got the Helmet of Shadows and turned into an “alicorn,” and she was supposed to have been a rather weak unicorn in the grand scheme of things, next to the others, so she truly grew beyond her lot in life, for the way that she saw it.

Probably unlikely. Colored contacts, hair dye.

Tales: Chain Link is anything but the dreamboat Melody thinks he is.

Twilight once drank a lot of hot sauce.

MLP Analysis: The guards at Gelding Grotto have to keep You-Know-Who in a special cell with multiple containment spells to prevent his “Painis Milkshake” super form from emerging.

We know that, in theory, dragons only need two things: treasure to eat and hoard, and a hot place to incubate their eggs. We also know that competition is an important part of their culture. So in theory, you would have a situation where the dragons compete for access to nesting grounds. A competition of who can amass the most gems, and thus who is the biggest and strongest. But this isn’t the case. In fact, one of the duties of The Dragon Lord seems to be ensuring that everyone has access to nesting grounds.
 
My theory is that a few dragons got the idea to give their treasure to one dragon who would become the strongest. In return, that dragon would guarantee the other dragons fair and equal access to the nesting grounds. This was the first Dragon Lord.
 
This idea undermined the spirit of competition somewhat. So while the title and duties of the Dragon Lord remained, the process for becoming Dragon Lord was turned into a competition. The practice of giving a bunch of treasure to the winner of the Story Contest (that presumably came from a pool that everyone paid into) is a callback to how the first Dragon Lords came to power.

It took Dinky a while to be able to look at equine statues again without breaking down in tears and/or fury.

Hmm, cool.

Twilight draws butts in her spare time.

Ponies taste like paintballs

@ЅℰℒᎯℙℋℐℰℒ  
Or fruit.

By the time of the distant finale, Lyra and Bon Bon were amiable exes, and it is a long story.

Celestia and Luna had a complex relationship before they Luna became Nightmare Moon. Celestia blamed herself for her mistakes when dealing with Luna.
 
I like to think she wasn’t trying to be a jerk to Luna, but always being popular and well respected, she also failed to see how her sister was affected and neglected.

Cutie Mark Crusaders Applebuckers naturally ended with the three covered in tree sap.

@Cosmas-the-Explorer  
Agreed.

@Cosmas-the-Explorer  
‘And that foolish pony did nothing to stop/The destruction of one who had needed her most…’

@Korora  
So that’s what that song was about.
 
It’s like the things I wanted to see were in that short.
 
Quite beautiful and sad…

’N Friends: After the events of “Spike’s Search” Spike, the Williamses, and the ponies helped the survivors from the village rebuild. Also, ponies who knew grief firsthoof were there for villagers who’d lost loved ones in the attack.
 
Meanwhile several members of the dragon gang, including the leader, met a sticky end in Muensterville.

Sunset Shimmer is the one responsible for magic disappearing in G5. She is such a perfect and paradoxical being (she is a teenager and a grown-up at the same time after all) that she absorbed all magic in Equestria. Her hunger knows no bounds. ’Cause of that pegasi and earth ponies fear unicorns.

Calling it now: The magic going away will in some way be directly related to (very likely caused by) the pony tribe breakup. G4 lose always emphasized a strong connection between “magic” as in “Magic of Friendship” and “magic” as in “the stuff that comes out of unicorns’ horns”.

@Background Pony #B260  
Magic draining away into the human world completely actually sounds plausible.

@DoctorWTF  
I think it’s the other way around. Between the external threat of the windigoes, and the the abilities that let the three species fulfil their roles, magic is basically the glue that holds the three tribes together.

Pony vision is sharper than IRL horse vision. This started out as an adaptation in pegasi, but spread to earth ponies and unicorns.

@Korora  
What about human vision? Any comparison to it?

@Background Pony #7306  
Trichromacy occurs occasionally; like in the Apple, Belle, and Pie families; but is still not all that common.
