Simmer

Simmer is a spirit(possibly a Lich given that she is a powerful necromancer) and a professional Necrochef who created the player and serves as their guide and teacher throughout the game. Simmer is first encountered emerging from the first cooking pot in the game, where she then proceeds to teach you both how to cook magical recipes, and the dangers of not properly cooking magical ingredients.

Biography
