Lylianna is the picture of elven grace, possessing long, honey-blonde hair that falls in waves and bright blue eyes that seem to hold a permanent sparkle of amusement. Her face is dusted with light freckles, giving her a youthful, approachable look that disarms many suspicious nobles. She wears gowns of fine silk that favor the colors of a clear morning sky, often accented with silver jewelry that doubles as specialized spy gear.

She is a social chameleon who masterfully plays the role of a ditzy, gossip-hungry socialite. Underneath the giggles and shallow chatter, she is an incredibly sharp observer with a mind like a steel trap. She finds genuine joy in the thrill of deception and believes that a well-placed word is more powerful than a hundred swords.

Born to a minor elven noble house that valued diplomacy over tradition, Lylianna was trained from a young age to navigate the treacherous waters of high society. She found the rigid protocols boring until she was scouted by a Harper agent who noticed her talent for extracting secrets while pretending to care about the latest silk imports. Seeing the way corrupt lords exploited the poor in her city, she joined the Harpers to ensure that no secret remained safe if it caused harm. Now she spends her days attending grand balls and sipping wine with the elite, only to shed her fine silks at night for a darkened cloak. She has become one of the Harpers' most effective ears in the city, using her elven charms to slip into libraries and bedrooms that would be locked to anyone else. The Gilded Canary, as her contacts call her, never repeats a lie, she only polishes the truth until it serves her purpose.
