The strong ans silent type

Diamond Dust Pie
(they/she, agender, Lesbian)
-Only daughter of Rarity and Maud Pie
-aloof and confident, they are often the brains behind the scenes. They know a lot more than they let on about most things.
-Shes a mediocre spell-caster, with a special talent in gemstone and crystal art. She makes her living running a small business of custom handmade jewelry.
-They have a large circle of friends, but most of those ponies aren’t actually all that close to Diamond. Diamond keeps a lot of ponies at arms length, thinking that they only really want to hang out with her under false pretenses.
-Diamond is relatively happy and well adjusted, but kind of feels like neither of her parents are all that happy.
-Rarity and Maud are very good parents, but don’t really love each other. They were very passionately in love when they were young, but have grown apart as they have aged. Rarity especially feels like perhaps she would be happier if she had been with someone else. They both try to keep this from Diamond, but their foal isn’t stupid and knows that they’re the only reason that Maud and Rarity are still married.
