Aboard the slaver ship, Romana is freed by another Tharil named Lazlo, and she hides in the hull. She encounters Adric; the two work out that the ship is made from an incredibly dense dwarf star alloy that can contain the Tharils. K9 arrives, and informs the two of dimensional instability in the null space, which they attribute to the alloy, causing the space to collapse in on itself. Romana rejoins Lazlo, and takes her to the gateway and through the mirror, while Adric remains aboard the ship.
