What Ember didn't know, in the middle of her magic lesson, Erlos had come to the training grounds and sought Draven, informing him that one of his aides, Wind Fae Melion, had come back to the palace and was waiting in his study to report something urgent. That was the real reason why the King had left.
After Ember's lesson, Helia went to the King's study. As per her usual practice, she would report the results of the day's lesson to Draven. However, Erlos told her he was still granting an audience to Melion, and thus, told her to wait for her turn to talk with the King.
By the time their meeting finished, Helia had enjoyed a cup of tea in the reception room next door.
Helia paid her respects to the King. "Greetings, Your Majesty."
Draven accepted it with a light nod and commented on her expression, "Is she having trouble learning today?"
