Clairby was a short man with a pinched-up face and skin the colour of newly turned damp earth. He worked with the Bene Gesserit as a transport expert. Clairby drove numerous Reverend Mothers to an inspection of Sheeana's activities on Chapterhouse trying to culture sandworms, though on another job he was grievously wounded in an accident and was only saved by having cybernetic implants added, making him a cyborg.
