Readers have already seen Grisha do meaningful military things with their powers, such as propel the sandskiffs and throw flames at the volcra. This demonstration for the nobles, though, perhaps cuts into the idea that the Grisha are an absolutely essential element to Ravka’s military strategy, helping explain why peasants aren’t so enamored with the Grisha. Indeed, this is the King’s party, and in general he seems more interested in beauty and spectacle than in practical things. This party, on the whole, may reflect why the wars in Ravka persist: the King is either not committed or doesn’t care enough.
