Why “muisak” is a great word
MUISAK — [Noun] The vengeful, disembodied spirit of a person whose head was taken and ritually shrunken into a tsantsa. Borrowed from Shuar muisak. Unlike a tsantsa (the preserved, tangible trophy) or an arutam (a sought-after ancestral power-spirit), a muisak is a specific hostility born of violation, a wraith tethered to its own defiled remains. It is the angry hum in the still air of the trophy-house, the sickness that follows the trophy home, the weight of a gaze felt from an empty corner—the permanent, intimate revenge of a person turned into an object.
