I noticed now that the Maker was left out in the depths of space so it wasn’t captured and destroyed. So we could have a Shedai in a later story.
Actually, by the time the Wanderer opens the Conduit to the Progenitor, the Maker has rejoined the Colloquium (see p.227). She is captured along with all the others when the trap is activated, and she is destroyed with the others at the novel's end. Post-Vanguard
, the Shedai are no more.
