A member of the first Jesuit expedition to Rakhat aboard the Stella Maris, Robichaux is captured together with Emilio Sandoz. Purchased by the merchant Supaari VaGayjur, both undergo hasta'akala, whereby the tendons of their hands are severed between the bones, lengthening the fingers and rendering them incapable of supplying one's own needs. Marc bleeds to death and is thus spared the repeated rape suffered by Emilio.
