There is reliable information that the lord of this castle has enriched himself well during this time and is going to soon export gold to his estate. Robbers from all over the area immediately hid in the forests in anticipation of such a fat prey. We could offer escort and protection of gold on the way, but the lord will hardly entrust us with such a task. We could lighten the chest before the gold is sent to the bandits out of the way. You just need to sneak inside the fortress, right into the lord's house.
