The Bastard of Linan had to attend an evening gathering of youth where he met the noblemen of the capital. In his disguise, Arthur made idle chats with the people just to assert his existence.
The hustle was a chore for Arthur, who wasn't used to interacting with strangers for so long. However, Master Ronin said that he needed to give himself a background.
Despite the ridicule and discrimination, no one asked about the origins of a bastard son. This would bring the affairs of nobles to the surface and these were ugly.
In the gathering, Arthur saw Caleb surrounded by his entourage of noble youth. Jerano wasn't solely for nobles, but it was a common aim for this. This made the commoners who enrolled there to be oppressed by their noble peers.
