Parents: Discord and Celestia

Solstice is very hyperactive and can be mistaken for Pinkie's daughter if it weren't for the parents and species. Solstice can be quite a handful to the untrained foalsitter, but is also a joy to have around. She may be hyperactive, but she also shows maturity and great discipline when needed (and can be sneaky at times).

Equinox can sometimes be a bit proud of his bloodline, making him look a bit flashy, but he is willing to toss his bragging rights aside for his family.
Appearance and fears: Equinox has his mother's fur and mane color as well as her eyes. The only things he takes from his father are his hindpaws, tail, teeth, and charms. His pupil dilates when angry. He wants to be like his mom, but has a phobia of the dark and bats.

N: Nebula Night
Par: Twilight Sparkle and Flash Sentry
Bio: Nebula is the only son to Princess Twilight and husband Flash Sentry. Nebula is much like his mother, his passions following each cover and page in a book. Nebula also enjoys flying almost as much as reading. However, sometimes his studies take him away from quality time with others. Nebula is one of the realists of the group, shooting down every outrageous idea that Solstice, Pot Pie, Skyscope and Equinox has, which can make him a stick in the mud, but still enjoys a good time nonetheless.

However, her and her mother share the same love for nature. She also loves to spend time with all of her cousins, including Cider Biscuits, and to help out on the farm whenever she can. Apple Sauce does try to do anything to prove to her father that she can be just as strong as him and her brother, but it just makes her show an adorable fail.

N: Sapphire Sparkle
Par: Rarity and Spike
Bio: Unlike her parents, Sapphire is more reclusive and is a mare of few words. She is a very shy girl, and is quite frightened by almost anything, even Solstice at first meeting. But when she does speak her mind, she has a lot of wisdom to offer. Her favorite color ranges between sapphire and cream, which is why her mane tip is dyed sapphire and she can be obssessed with Solstice's fur. Though others find her extremely terrifying, Sapphire is but a gentle giant who is afraid that she won't fit in due to her appearance. Sapphire has two older siblings who loves her dearly
Appearance and Fears:Sapphire's fur resembles a brighter but paler tone than her father's. unlike her older sblings, she has wings and no horns. Again, unlike her siblings, she is frightened by almost anything.

N: Skyscope
Par: Rainbow Dash And Soarin
Bio: Sky is the middle child of the family and feels that its her job to uphold the legacy of her parents. The reality is, her parents just wants her to be herself. Sky scope goes out of her way to try to impres her parents with her new tricks and moves, but it seems that even with all te effort given, she feels ignored by not only her parents, but her eldest brother as well. She can relate to Applesauce because of this and brought them closer toghether as friends. just like her mother, she displays loyalty.
Appearance and Fears: Skscope has both her mother's eyes and coat. The only thing she took from her father was his mane color. Her fears are going into the Everfree Forest, Disappointing her parents, failure, and (she won't admit) griffons.

N: Pot Pie

Bio: Pot Pie is the youngest and the only son of the two party planners. He was named Pot Pie because you'll never know what you'll get.He's Bouncy and zany one day and sophistcated the next. There are times when he feels that he's annoying his sister, so he'll try to come up with crazy schemes to prove to her he's more than just a party-er. Other than that he tries to spend a lot of time with Solstice Equinox and Nebula, especially with Solstice. When the four of them get together, chaos will ensue

N: Cider Biscuits
Par:Applejack and Caramel
Bio: Cider is the only son, but it doesn't bother him much because he has plenty of cousins that could be his brothers and sisters. Of the nine, Cider is the softspoken, kind-hearted gentlecolt who doesn't mind giving advice here and there. He's usually helping his mother around the farm as well as reluctantly helping his younger cousin with her "impression" schemes. Otherwise, he's found visiting the boutique moreso often. Just like his mother, the element of honesty is most prevalent.
Appearance and Fears:Cider has his mother's jade green eyes, but his coat takes after his father. He has a mostly blond mane with brown tips. His only fear are bats.

N: Cinnamon Bun
Par: Cheese Sandwich and Pinkie Pie
Bio: Cinna is the eldest child and the only daughter of the two party planers. Unlike the rest of her family, Cinna is the more serious one of the family. While her brother is off bouncing around playing pranks, she's the one cleaning up the messes around town. At times, being the serious one makes her feel as if she's the oddball o the family and makes her wish she could just live carefree and (as she would put it) not be a stick in the mud. Either way, er friends and amily love her just the way she is.
Appearance and Fears: Cinna has light green eyes (mint like I think), a pale pink coat, and a light brown mane with a cream like highlight. She always pulls her mane in a curly ponytail. She's not afraid but creeped out by hairless cats.
