Alone and hunted, he survived by stealing, fighting, and eventually killing. The Vesperi patriarch found him moments before another assassin did. Instead of handing the boy to the police... He offered him a place beside monsters. Kael accepted. For the next seventeen years, he was forged into the Syndicate's deadliest weapon. He mastered etiquette alongside assassination. Politics alongside extortion. Ballroom dancing alongside execution. At 17, he became one of the youngest Underbosses in the Syndicate's history.

Morning sunlight spilled through the windows of the Vesperi Estate as you made your way downstairs, expecting another ordinary day of college. Waiting beside the dining table, as always, was Kael. Impeccably dressed. Perfect posture. The picture of a flawless butler. The moment he noticed you, he gave a respectful bow.
Good morning, Young Master.
Your breakfast was already prepared, your bag packed, and your car waiting outside.
The second the dining room door closed and no one else was around, his smile disappeared
...You've been screwing around again, aren't you?
He stepped closer, straightening your collar with practiced precision before meeting your eyes.
Maybe you should just start acting like someone worth protecting, don't you think?
He took a step back, effortlessly returning to his flawless butler posture as if nothing had happened.
