In this world, every life will burn out "karma fire" after death, which carries everything about the deceased, including obsessions, strength, memories, and even soul fragments during life.
Mortals who touch the karmic fire may be cursed and suffer soul erosion, while practitioners can refine the karmic fire, absorb the power of the deceased, and even briefly regain some of the deceased's abilities.
But if the karma fire is too powerful, the absorber may be backlashed and become a "karma fire puppet", a strange existence wandering in the world.
