Fnar, the unborn child who lived in Hell for... um... we don't actually know how long, could be months, years, centuries... picked up a playmate or perhaps a toy: a Rework, Bonavin. He grew to be very protective of the boy, which makes little sense since Reworks are mindless killing machines.

Here he is depicted in a scene from a fanfic I did, facing up to the Devourer. Fnar is, of course, quite oblivious.
