The hawk is a predatory bird. It was the symbol of House Atreides.
This symbol was used on Atreides uniforms, ships, and various crests and pendants, throughout Atreides rule of Caladan, Arrakis, and the known universe.
It was said that Paul Atreides as Muad'Dib, when he witnessed a young hawk emerge from its shell, muttered: "Kull Wahad!"
