Attractors are almost superhuman beings that have unique abilities. Called "Larva" by Custos, these humans with abilities emit some sort of signal referred to as "Larva Burst." There are a few stages of a "Larva Burst" in which the Attractor's abilities begin to react more strongly to their surroundings, ultimately taking over the body if the burst is not controlled. Usually an Attractor will gain his/her abilities through psychological stress, such as loss of family, or being mistreated.
