Yeah so that's my current excuse as to why quite a few eqg kids are living in Equestria.

Anyway, this is more or less concept art- but I liked it so decided to post it. (AKA Heart Beat and Blue's designs aren't set in stone)

Everfree/Willow: The daughter of eqg!Gloriosa and eqg!Applejack. That's all I got so far :P
Oh, besides her eqg version.

Equestrian Magic: The daughter of eqg!Rarity and eqg!Twilight. (Rarity and Sour Sweet are swingers or something; I need a way for Rarity and Sci-Twi to be on good terms yet have a kid) So this pony here got so fed up with her human life that she went to Equestria to start anew. However, she was immediatley halted in her tracks- as it turns out she's got a cracked horn! (Idk, maybe it's got something to do with an injury she sustained in the human world) She's definitely not an upcoming villain.

Blue (b/c I couldn't come up with a better name): The son of eqg!Flash and eqg!Derpy. He heard about this world where everyone was horses and got curious. That's about it for his origin story. Currently, he's studying (actually stalking, but he doesn't know that) the wonderbolts to learn how to fly correctly.

Heart Beat: The daughter (formerly son) of eqg!K-Lo and eqg!Su-Z. She loves her parents and all, and they love her, but she really wants to get away from her human life being constantly pressured into the music scene. Her parents don't quite understand that she's not interested. Also, her and Carmine basically grew up together.
