Character Synopsis:
Diana Leia Sentry was raised in luxury within the Crystal Empire, the very kingdom that was trapped behind the mysterious fog that kept them trapped. For the majority of her life, it's always been just her with her mother and uncle since her father was captured by their enemy right before the mysterious fog appeared after her mother performed a spell that sent the enemy out of the kingdom and made the Crystal Empire trapped behind the fog, letting the kingdom itself become nothing more than a myth to the world.

One thing about Diana is that she's always wondered about her older sister that was sent away before she was born and since her mother didn't want to hide anything from her, Diana was told everything about Briana, her older sister that never got the chance to stay with them. Her whole life, Diana has dreamt of meeting her older sister and always waited and waited for the day that Briana would return home to them.

But when that day comes, Diana suddenly finds her life being thrown into the dangerous world that her older sister grew up in as old and new enemies are around every corner. Now, her life will never be the same as it once was before.

Physical Appearance:
Diana has blue hair that has purple streaks in it and violet eyes. She also wears black glasses in order to see far away. Diana wears a sky blue striped pink shirt, a pink skirt with white stars on it, short socks, and pink leather heeled shoes with white laces on it.

Personality:
Diana has her mother's intelligence and her father's loyalty. She has a great interest for science and knowledge as she also loves making creations. Diana is very sweet, kind, and trustworthy but unlike her older sister, Diana is a bit more serious than Briana and isn't naive at all, making it so Diana doesn't fall for any manipulative from their enemies. Unlike Briana as well, Diana doesn't hide her emotions either and when she's upset, she lets it out instead of keeping her emotions all bottled up like Briana does.

Although Diana does believe in second chances and gives forgiveness towards someone that she isn't sure can be trusted, she is skeptical towards that person and likes to see the proof that the person has indeed changed, unlike Briana who would forgive the person straight away without thinking if the person could be faking it or not.

Quotes:
[ongoing]

"John [OC owned by @GeekyCookie1] was right about you, you know? You're a coward because the only reason you kept the truth from him was because you were never worried about him, weren't you? No, you were only worried for yourself because you couldn't handle the thought of being a monster so you decided to let John [OC owned by @GeekyCookie1], my best friend and the guy that I love, become the monster instead. Well, guess what, Briana? John [OC owned by @GeekyCookie1] may have left to join the Foot Clan but he's not a monster, you are."

"We may be sisters but as far as I'm concerned, we are not friends. You know, if you had just trusted me with what you knew about John [OC owned by @GeekyCookie1], then maybe things would've ended differently but you didn't and that's on you."

Other Facts:
[ongoing].

1. The friendship between Kaz and Diana is kinda like the friendship between Eugene and Cassandra in Tangled The Series but as a friendly rivalry between a brother and sister that playfully make fun of each other and all.

2. Unlike her older sister, Diana was never sent away from her family and remained in the Crystal Empire.
