The wilting beast that defies death itself. Its body has long started to fall apart, the creature having exceeded its lifespan decently. Despite this, a particular species of butterfly that feasts on flesh and blood was attracted to the defiant monster and started to take up residence along its body. While this would seem disadvantageous at first, in reality the insects had themselves incorporated into its very flesh, the largest and most outlived of the species digging their legs into the back and eye sockets where they proceeded to take up the function of eyes and wings. While the body, mass and prey of this silent hunter is given to the butterflies, the mobility, protection and shroud of the swarm is given to the beast itself.
A strange and terrifying symbiotic relationship that extends beyond the afterlife.
