Saurian Old One

The only clean account of an old one's death involves no fight. A woman walked out to it with water and a length of ribbon and led it into a town, where a frightened crowd killed it while it stood still. The town holds an annual procession of apology. Every other attempt ended in a casualty list and a crater where a hill used to be.
