It seems that there was more than just one fight just before dawn. Ariziya attacked Captain Inaya and the pair exchanged blows and shap words before the Irzali youth pulled what seemed to be a wooden blade on her, but he dropped it and went out into the fog scarce minutes after the monsters had retreated.
Even more confusingly, he ran in moments later yelling that he'd seen a huma bird and that the ship was saved!
