The Story of Fiddlesticks
Before the first city was built or the first language spoken, something walked in the darkness between conscious minds. It fed on fear — not the ordinary fear of predators, but the deeper terror that wakes you in the night with no name, the certainty that something is wrong without any evidence that it is. Fiddlesticks is that something. It has been here since the beginning, and every sentient creature alive carries an ancestral imprint of what it is.
What it wears — the scarecrow shape, the tattered form — is a camouflage assembled from the nightmares of those it has consumed. It has worn many shapes over Runeterra's history, because it learns from what terrifies, and what terrifies changes as cultures change. The current form is borrowed from memories of agricultural communities, of the uncanny in the field at night, of man-made things that move wrong. It updates its appearance the way predators update hunting strategies.
Fiddlesticks does not want to destroy Runeterra. Destruction would end the food supply. What it wants is for the fear to continue — the inexplicable, creeping certainty that something is wrong. It is ancient enough to be patient. It is patient enough to be satisfied with small, sustained feedings across generations. The legends communities tell their children about things in the dark are, partially, Fiddlesticks keeping its profile warm.
