The Story of Vayne
Shauna Vayne was a child of Demacian nobility when monsters murdered her family in front of her. The experience didn't break her — it carved out everything soft and replaced it with a single unbreakable commitment: the supernatural evil that hides in the world's shadows will not go unchallenged. She trained with Demacia's hunters, then exceeded them, and then left them behind when their methods weren't sufficient for what she'd decided to do.
The Night Hunter works alone because partnership introduces variables she can't control, and uncontrolled variables get hunters killed. She studies her targets methodically before moving — tracking behavioral patterns, identifying weaknesses, preparing contingencies. What others call obsession, Vayne calls thoroughness. She has a list, and she works through it with the patience of someone who has accepted that this will take her entire life.
Her relationship with Demacia is complicated by the kingdom's brutal suppression of magic — the very thing that makes magical monsters so dangerous also makes the people who might fight them legally suspect. Vayne has never been comfortable with the politics of her homeland. She serves the function Demacia needs without embracing the ideology that makes it possible. The night is where she lives now, among the things the daylight world pretends don't exist.
