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.
Clairby died after taking Darwi Odrade, Dortujla, Suipol and Tamalane to Junction to meet the 'Spider Queen', as he destroyed his vehicle before it could be taken by the Honored Matres. However Clairby was promised another life by the Bene Gesserit as a ghola.
