Older Trixie Lulamoon

Remake of this.
Married to Prince Blueblood, Trixie Lulamoon Sparkle is new to this royalty thing, and she's living it up for everything she can. Jewelry, fine fur, glass slippers, diamond studded fur, opals, sapphires, gold necklaces, her entire wardrobe costs more than many ponies make in a year. Frankly, she doesn't care. She's still Trixie, unfortunately, and she has let her status go straight to her head. Full use of the ROYAL CANTERLOT VOICE at all times, an insistence on being addressed as 'The Regal and Majestic Princess Trixie'. She's Twilight's extremely estranged sister, to the point that after Twilight got her cutie mark, Trixie ran away and they hadn't spoken in years. The surprise for the rest of the Mane 6 being told this when Twilight was invited to Trixie and Blueblood's wedding was an extreme surprise, obviously. Not fun, but at least it went off better than Twilight's last 'Surprise, I have a sibling and they're getting married' debacle (Hard to be worse than changeling invasion, though). She has a son now, Prince Regality Blueblood, who has defied the odds of his parentage by being a really great guy, although as a colt he was a big momma's boy.
Trixie can be found prancing around Blueblood Manor, bossing her servants around like crazy.
