Rekur Van, a biological engineer and geneticist now reviled across the League of Nobles, squirmed in his life-support socket, unable to move more than his head because he had no arms or legs.

Shortly after capturing him, Erasmus had seen to the removal of the man's limbs, rendering him much more manageable. He was certainly not trustworthy, in sharp contrast with Gilbertus Albans.
