The rook is a skilled survivor. He is ancient and has inhabited the planet longer than humans. This you can tell from his singing voice: his cry is harsh and grating, made for a more ancient world that existed before the innovation of the pipe, the lute, and the viol. Before music was invented he was taught to sing by the planet itself. He mimicked the great rumble of the sea, the fearsome eruption of volcanoes, the creaking of glaciers, and the geological groaning as the world split apart in its agony and remade itself.
