History: Crystal sky is a quiet pony who spends a lot of time reading. when she was just a filly, she found a beautiful peice of tin foil, that was the exsact same color as the sky. she took it home, and grabbed a pair of Scissors. Soon enough she had created a diamond looking peice of tin foil, that of course, was the exsact same color as the sky. she found it beautiful, and off she went collecting more things to use to make diamond shaped items. but they were always that beautiful light blue color across it. soon enough she got her cutie mark. As she grew up, she actually opened up her own shop. in this shop, you can buy all sorts of diamond-looking items. now at her current age, 20, she STILL has the shop open and always loves seeing so many ponies come in everyday. she has her shop up in ponyville. she also lives there. and shes always happy to make new friends, she doesn't have thousands of friends, but she does have quite a few.
Example RP Segment: Sky walked through the streets of ponyville. it was sunset, and she had just closed up shop. Sky sat by a fountain and looked around. what to do...well there wasn't much. her friends had gone home to chill out, she didn't want to disturb them. the shop was closed, so there's no point going back there. Sky gave up. there's nothing to do at this time. Sky trotted home and went to bed. Hopefully there was more things she could do tomorrow.
"Harmony, of course!"
