Based on DisneyFanatic2364's CMC: The Next Generation. It's the next generation after that, and there are three new fillies who want to get their cutie marks!

Jany: The white chaotic Earth Pony who loves to play pranks on ponies with her chaos magic. She is the daughter of Zany, The Prince (now King) Of chaos.

Fluffball: The purple pony/changeling/draconequus, daughter of Screwball and Mothball. She gets bullied quite often for her looks, and she has both changeling and chaos powers.

Sun Ray Dash: The light blue Pegasus that, unlike her mother, could fly as a filly. She is bullied by Cinnamon Apple, the school bully, but also the colt who used to be her favorite cousin.

There are some events that overlap with PhoenixTDM Adventures in Equestria, but it's not a required read.

Edit: I am currently making a comic adaption of the story! Read it here!
