These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Strangled by the Red String: Ira Hath makes a prophecy before she dies for the Manth travellers as they're about to reach their homeland. This includes telling them who they will marry, and how many children they'll have. Only one or two of them had any inkling of an attraction before this, but of course they really do all end up married to their prophesied partner in the epilogue. Ira may have only been suggesting matches that she had already noticed developing among the group members, but none of these developments were ever shown to the reader.
