When a stranger that she is familiar with comes into town, she finds herself questioning as to what to do and how to accept a secret they have held from her since they meet.

Sometimes, friendship is tested by what your willing to see as truth or lies. But how can one trust those who live with using masks to hide both lies and truth?

This story is a sequel to Converted

This story is a sequel to Celestia's Twilight

We all know the story. One thousand years ago Princess Celestia was forced to banish Nightmare Moon to the moon to save all of Equestria, but what if Luna had been hiding something from her sister, scared of how she would react? When Luna had no other choice, she cried out for Celestia and Celestia came. For one thousand years, Luna wondered what happened when Celestia left; now she's finding out...

But is it already too late, or will Luna be able to take the role she had so long dreamed of? The dream of being a mother?

editor Don't Look At My Name Bro! and RK I am lost without you!

A thousand years ago, Princess Celestia banished her sister to the moon, that much we know. What wasn’t known, and what Celestia kept secret was that before her banishment, Luna had given birth to a foal. Now a thousand years later, as Nightmare returns to Equestria to bring about Eternal Night.

Twilight Sparkle, protege of Princess Celestia, struggles against the tyranny of this ancient foe. But how will she be able to save herself and her friends when the truth of this ancient legend crashes down upon her? Twilight will have to confront herself...and her heritage.

Twilight Sparkle wakes up after using an age spell on herself to try and make herself more mature but it does the opposite.

Princess Celestia comes to see Twilight and tells her friends that the only way Twilight can be restored is if she grows up naturally

Spike is taken to Canterlot by Princess Celestia before the age spell is cast.
This is based before Magical Mystery Cure.

Twilight Sparkle has lived a full life but now she's a 115-year-old pony lying on her deathbed and waiting to pass on. As her time draws near, she receives a visit from a mysterious mare who has come to seek out the answer to a simple curiosity.

Its been a long time since Twilight had written a letter to Celestia. So much had happened. So much that Twilight felt it would be good to contact her old mentor and tell her just what had been going on since they last talked. But for some reason, this letter feels different then any other sent. This one, seems like the most hardest one she has ever had to write.

This story is a sequel to Dear Princess Celestia

It has been three months and fourteen days of silence from Princess Celestia. Twilight has suffered from insomnia, anxiety, depression, and malnutrition. Spike and her friends have tried everything they could think of to get her to spend time with them or take a break outside. Nothing has worked and just when everything seems hopeless, a letter arrives. A letter from Princess Celestia, though something seems a bit off.

Changelings and ponies had always been natural enemies of each other, especially with the crystal ponies when they were around. Why wouldn't they be? Changelings were like parasites, feeding off the love that ponies gave off and driving them to illness.

However, Changelings had begun to decline. What started out with as seven hives have diminished down into three, all of which had gone into hiding so well that most ponies didn't know what changelings even were. Even Celestia had not seen one for quite a while, a long feat for an immortal pony.

Until she found a nymph. A new Changeling Queen.

Unable to find it within herself to abandon the changeling, Celestia ends up taking the nymph back to Canterlot under guise as Twilight Sparkle. The plan was simple; find the hive that Twilight belonged to and return her back to be raised with her race.

Of course, despite everything she learned through her long life, she had forgotten that things were never that simple.

For starters, she did not anticipate herself to grow fond of Twilight as time began to pass, or to beam in happiness when Twilight began to refer to her as mom.
