"I thought about how could Manohar and I get fooled by the Skinwalkers and I think I know the answer." Lith replied. "You see, the life force is a three-dimensional form of energy, yet when a healer looks at it, they only examine the surface because it's there that the signs of an illness or of a slave spell can be found.
"Yet a Skinwalker is different. They rearrange their life force to mimic that of their victim, folding and rearranging it until they match. It means that since their victims have no runes on their life force, the Skinwalkers probably turn their own inside out so that when a healer examines them, they look normal."
"Good gods! We need to alert the army and have every city official checked again." Kamila said.
