Arthur has nothing to, so he is searching for a way to get some money other than conforming to feudalism. He found an interesting tree while looking around for employment.
"It Is Dangerous To Go Alone Take This"
Victor is scheming to get all of the money that the king has out of spite for the king, then he will leave the kingdom in chaos. Victor has rose to a spot of favor of the king even though he hates the king.
Bartholomew is waiting for somebody to stop Victor because he knows of his plans even though he is not able to tell anybody in the kingdom.
Bartholomew tells Arthur that he is the one who needs to stop Victor, so Bartholomew gives Arthur what he needs to stop him.
Arthur uses the "sword" that Bartholomew gave him to thwart Victor's plans.
Since Arthur saved the kingdom without anybody knowing, he figured that he could help himself to the treasures Victor would have taken.
