A plant that feeds on sound instead of light, a silent creeper hides in the shadows of other forest plants, emanating an aura of absolute silence as they magically absorb the sounds around them. The nourishment a silent creeper derives from a given sound is unrelated to its would-be volume; a noise that would have been loud sustains it no better than one that would have been faint. Instead, the pitch of the silenced sound determines its nutritional value. Specifically, silent creepers derive the most nourishment from silencing the screams of the dying.
Because of this, silent creepers are driven to hunt and kill, or to lurk near other creatures that hunt and kill. When not feeding off the screams of another monster's prey, a silent creeper instinctively targets lone travelers and stragglers separated from their groups. A silent creeper that kills such a creature has no use for the creature's body once the killing and screaming is over, as the silent creeper derives no nourishment from dead flesh. Accordingly, it will leave such bodies for local scavengers to consume, spurring the growth of scavenger populations within its chosen hunting grounds.
