Mi Munequita Preciousa  
Princess of Sport [Most esteemed Crystal Jouster and Lacrosse]
 
Moon may look like a delicate flower but she’s actually very sturdy for a Unicorn. Some like to say she has earth pony strength like her mother 
Whatever the reason she’s a power mare who competes and trains regularly. 
She’s confident but soft spoken and spends a great deal of time harassing her royal guard platoon [particularly Flash Sentry]
 
Rosequart Lustre  
Princess of Science [Well educated Scholar and earth pony scientist]
 
Like her younger sister Moon, Rosie looks like she’s out of place in her profession. As a robust pink earth pony mare, she’s often not even recognized as a princess…by idiots [Rosie: GOSH if someponies would just open a newspaper once in a while!] 
All that being said, Rosie is very competent and friendly as a scholar. She does like to be pampered a little bit more than her sisters but she’s quite happy to take care of herself. 
She’s also known to listen to Death Metal as she works in her lab as she claims it helps her think.
 
Flurry Heart 
Princess of Fun [Head party planner for the Crystal Empire]
 
Flurry isn’t my character [duuuuhhh] but this is what she ends up doing in my universe 
She takes a lot after her aunt Pinkie Pie and begins planning parties for the ponies of The Crystal Empire however her true occupation is akin to being a mayor.  
She was groomed early on by her parents on how to take care of The Empire and she’s very efficient at her work, leaving her tons of time to do as she pleases.
