In the jungle there’s a parasitic fungus that penetrates the exoskeleton of ants. It grows inside their bodies, eating the ant from the inside. Soon the ant is as much fungus as it is ant. Once inside the brain, the fungus modifies the ant’s behavior, making it leave the colony and climb to a leaf overlooking the colony’s path where it grips a leaf with its mandibles to secure a sniper’s perch. After the ant starves to death up there, a stalk emerges from the ant’s brain. The stalk even knows which direction to grow in order to best position itself, before erupting and raining spores down on the ants below.
Sometimes I think a similar parasite has infected humans, one that uses mind control to ascend specific individuals to great heights where their behavioral and idealogical influence rains down on the public.
