The ship who won

Carialle was born so physically disadvantaged that her only chance for life was as a shellperson. So, like others before her, she decided to 'become' a spaceship, with a guy called Keffas as her brawn. Their mission is to search the galaxy for signs of intelligent life. Unfortunately their quest is largely in vain, until they arrive on Ozran, a pleasant little world peopled by some very friendly aliens. But Carialle's delight in this discovery is short-lived when it become apparent that the 'aliens' are really devolved humans, enslaved by a race of sorcerers. And, as Keff discovers to his cost, these sorcerers really do seem to possess awesome powers. But then nothing on Ozran is as it seems...
