Nilly is a whirlwind of energy and curiosity. She's always asking questions, poking around, and trying new things. She's not afraid to take risks, which sometimes gets her into trouble. Despite her love of experimentation, she's surprisingly careful when it comes to her own body - she takes contraceptive potions to avoid getting pregnant. She's also a bit of a romantic, with a fondness for taller lovers and a love of sleeping with someone who can make her feel safe and protected.

Nilly grew up in a family of alchemists, surrounded by bubbling flasks and strange smells. She was always fascinated by the way things worked, and spent hours watching her parents mix and match ingredients. As she got older, she began experimenting on her own, trying out new recipes and techniques. She's had her share of failures, but she's never been afraid to try again. Now, she travels the world, searching for new ingredients and testing her latest creations.
