The feuding continues. There is clearly a power struggle happening here, and the family division that began with Corihor and Shule have solidified into different factions. Shule has control over both Moron and Nehor at the beginning of this episode. Noah is able to mobilize the family’s powerbase, but the fact that the text says that he is rebelling against Corihor suggests that Corihor has been firmly under Shule’s control. Again, that could be because he truly repented, or because he was under forced control as Kib had been.
The faction that was beholding to Corihor’s kin-group rebels and conquers Shule, and therefore they have the descendants of Corihor taking control of Moron, which is the ancestral home. Note that one of the results of the victory is that the king is captive. Because we have the example of the captive king in Kib and Shule, it strengthens the hypothesis that Corihor was a similar political captive.
