I'm not sure what you're asking. Do you want to make an NPC with alchemy? In that case I'll present the person who found a cure for the plague in my campaign. Her name is Sirtane Leroung, the sister of House Leroung's leading lady Eliasia Leroung. She is a professor in the Leroung university, who specializes in alchemy.
