Aym was teaching their new little sibling to fight. Their father, The One Who Waits, aka/Narinder, had found them a while back and wanted them to learn how to fight, perhaps become a new guard. So they told Aym to teach them, the better fighter and more serious out of Aym and Baal. Baal was off sleeping somewhere.

Aym hands his new little sibling a fake knife, "You will be given a real weapon when you learn the basics."
