At the Barkaley Barony training grounds, before Leofric's dungeon raid begins, Arthur met Waldo Barkaley, the eldest son of the Barkaley barony.
As the eldest son, Waldo had to lead the raid troops to raise the family name and serve as the Barkaley family's overseer for the soldiers participating in the raid. Waldo was so scared of what he would face that he didn't feel up to challenging the dungeon. Then Waldo's fear was instantly dispelled when Arthur said
"No worry Sir. I will protect you no matter what happens."
