Has Sevar gone fully over to Keltham, if not over to Iomedae as such? Keltham would want the souls of the Project Lawful women who were sold away.
But Keltham wouldn't have Sevar sell herself to that end, would be unutterably furious with her for doing it that way. This is as blatantly obvious as anything between men and women could be. Sevar has raveled somewhat of corrigibility; she would not mistake Keltham's will so wildly if she was seeking to return to him as his own possession.
