Anton the spaceship’s heart. Pietro its mind, Roman (the current commander, dextrous and capable, able to fix anything, control the robotic arm with millimetre precision, wire the most complex circuit board) its hands, Shaun its soul (Shaun there to convince them all that they have souls), Chie (methodical, fair, wise, not-quite definable or pin-downable) its conscience, Nell (with her eight-litre diving lungs) its breath.
