Aura absorption is the ability to perceive the aura of others and to absorb that aura. Absorbing the auras of evolved humans has been shown to allow the user to manifest their ability.
- Linda Tavara is the only character known to have this ability.
Linda can see the auras of people and animals around her. The exact nature of the auras is unclear, though Linda sees the auras as light surrounding the individual. "It's lik eeach person holds a star beneath their skin, each one begging to escape". Linda described the light of animals as "tiny auras". It is unknown if she constantly sees the auras of living things or if there is an "off switch". According to Linda, Ida May Walker's aura was unusually bright. It is unclear if this is a property of all evolved humans.
Part of Linda's ability also allows her to actually take the aura of others. This leaves the bodies of her victims withered. If her victim is an evolved human, she also takes their ability. After taking Ida May Walker's aura (and leaving Ida dead), Linda actually possessed Ida May's ability.
Taking auras requires close proximity and physical contact. In every visible instance of Linda's aura theft, she has touched her victims with two hands. Linda described the sensations associated with taking auras as "heat [traveling] up my fingers and into my chest, filling me up with white, loving light." She also said, "I could feel everything, their hopes, their dreams for the future, while they no longer felt anything at al. Their spark belonged to me now."
