Rasmus listened to the Jester's full story and who he was before he became a Jester. He was an ordinary farmer, but he learned the art of stealth, espionage, and assassination from Celline. He had the talent to learn those things and learned all three arts in just a few years.
The Jester met with Celline similar to when she met her end, being heavily wounded. He treated Celline's wounds and hid her from her enemies. During that whole week, he fell in love with her, but she pushed him away as she distanced herself from him. However, fate made them see each other more than once or twice.
Celline was tasked with embezzlement and stealing documents from corrupted low-ranking nobles and merchants. The Jester, who was a farmer was one of the many people that suffered from those people. Countless of times Celline came to rescue him as a token of gratitude for saving her life.
