At Threshing, the cadets who remain are presented with the chance to establish a bond with a dragon. If they succeed in this bonding, they are officially elevated to the rank of riders. They are given rider leathers and their own private room.
For those who do not manage to bond, they are given the opportunity to repeat the year with the hope that they will make it to Threshing again and get another chance to bond with a dragon.
During the Threshing, a cadet typically senses when a dragon chooses them, as it’s a feeling that resonates within. Similarly, they can also discern when a dragon has decided not to select them.
