Cynn has raven straight black hair, soft and wispy. She often wears green contacts over her warm brown eyes, as she often goes undercover to see what muggles and half-bloods are treated like. Her hair has streaks of dark emeral green, from birth to seperate her as unique from normal traditional pure bloods.

She is extremely extroverted to people she knows, but more subtle to new people. She has good imagination, and is able to think outside of the box, looking into situations carefully. She is sometimes sharp tongued, but has a true kind heart. She often doesn't express her thoughts. Her mind is extremely quick, and is highly regarded from her peers and teachers. She has a dark cunning side as well as a sweet as honey side.

Cynn comes from the distinguished Yuewen Family, famous for their dark trades, known as the Merchants of the Midnight Market. We control a vast, smuggling network, and is respected very well. Cynn lives in the Obsidian Manor, where the whole family lives. Her family consists of: Cassian Yuewen (father, very haughty), Stephania Yuewen (mother, soft hearted, very much of a beauty, quick with trades), Lysander Yuewen (older bother, 5th grader at Hogwarts already, a prodigy, already learning the family business. Their family is very well known, with a touch of fear and awe.

When Cynn was 8, she opened one of her father's locked trading crates. Inside was a dark, swirling cursed object that began releasing black smoke. Before the smoke could touch her, it froze up and sizzled away, to her confusion.
