Welcome to the Miracleverse! AKA, the Disliked Ships AU, but I don’t use this as a platform for hate. While the universe is slightly… twisted, they are all options that could have happened in the main TFIMverse. They’re a chance to do things with the… standard ships that people have, and using them in new ways, as well as a platform for interesting characters. I want to do some different things with the designs, so I may note the standard designs I tried to avoid with each design. These designs have been done for… an embarrassing amount of time, so expect a lot of the designs at once, I finally decided to upload them. But, since this is a canon character, and I did it today and yesterday, that doesn’t quite apply. So instead of ‘what I did different’ with their children, I’ll explain my design choices for each of them!  
There’s gonna be a huge dump of these, as I recently realized while I was thinking of what scenarios to do, that I didn’t have enough designs for the older ponies, and that means I’ll be working on a lot of them, so there may be a gap between the story pieces and the next one, as I fill out the cast of the show. This may mean more simple descriptions, though for some ponies, it’s just because a lot will be revealed later rather then just now, and the history isn’t as important. So forgive me for the shorter descriptions.  
This drawing is special! wanted to help with the Miracleverse, and since I have some trouble with hairstyles sometimes and she is the absolute GODDESS of hairstyles, I happily accepted. She drew most of this, with me making minor edits (thinning the hair so it was flatter and more limp, and coloring the bows), so she should take most, if not all of the credit!  
Marble Pie is the mother of Maltster Apple-Pie, the bastard (literal meaning here, Maltster is a pure boy) son of Braeburn Apple, and aunt of both Trixie’s kids and Limestone’s kids, and a distant (emotionally) aunt to Claystone Pie.  
While her sisters were off getting married or raising their current children, Marble was all alone, and actually quite upset. She had no one, and yet Limestone had Pegmatite as a daughter and Maud had Trixie as a wife… and yet she was originally the romantic of the five Pie siblings (Octavia Melody was born Obsidian Metamorphic Pie), the one pining after somebody to share her silence with.  
Ponies always assumed that because she was silent and shy, that she had no social abilities, but she had always longed for a fairytale romance to sweep her off her hooves. She knew she always wanted to work at the Rock Farm with her family, but she did want to share her life with someone else. Sure, it was mostly cooking and cleaning and other housekeeping, but it would be with somepony else. She felt a bit guilty that she seemed to be content in the role of homemaker, but it was her life.  
So she spent her life watching her family have some form of the life she craved, going to the market by herself and watching ponies go by living their own romances, pining after an imaginary stallion… until she met him.  
He was charming, handsome, and a farmhand just like her, and he had such a beautiful name; Braeburn Apple. Unaware of the (possible?) relation they had, she was smitten and Braeburn quickly charmed the shy and quiet mare into a one night stand. Even though Braeburn had no intentions of a lasting relationship and attempted to make that clear, Marble was a hopeless romantic, already picturing a picturesque life with him, and she visited him constantly at market where he sold apples.  
Soon she discovered she was with foal, and she knew she had to convince him to stay… surely he wouldn’t abandon her and their foal, right? This was when Marble learned Braeburn was spoken for, already Spitfire’s fiancee. He had slept with her before they were engaged, and had tried to explain many times, but Marble’s rose colored glasses covered up all the flags. Braeburn promised to pay so their foal would be taken care of, but he loved Spitfire too much to leave her for Marble over one night of passion.  
Maltster was born with complications, he was larger than the average baby and required an emergency c-section to save both of them, and they didn’t have much but the family doctor, who was not well versed in c-sections. Though the operation was successful, she would be left with a scar that would not fur over, so Maud offerred her dress to wear, which Marble keeps to this day  
She named her son after an apple and kept his name in Maltster’s in the hopes that Braeburn might come back and feel some affection for his foal, but he lives far away now and she has no way to know he lives at the village below Cloudsdale. So Marble raised Maltster on her own… well, with Pegmatite, Limestone, Maud and Trixie’s help (the rest too young to help or not born yet.).
