Pan: "Hey boss this is, ooof was he really worth that much? Was he that much of a high-ranking spell caster? I'm guessing it was a pretty fine."
Ares: "Yes."
Pan can notice Ares is not completely telling the truth and could guess it is more to buy his loyalty. Then actually what the individuals were worth.
Pan: "Well now that I got all this gold uh I think uh I think the boss can use some fresh equipment right I think."
Pan would reach into the chest, take out two gold bars, and hand them to Ares.
Pan: "That is my investment in our fortress. You could tell me to go back to the town, and I can order some new things. I'll get myself some new equipment. So next time when we want to capture, I don't know. Maybe ten spell casters at once. I could be ready for it, you know?"
Ares takes the bars and smiles with excitement.
Ares: "That often was too generous."
Ares would get up and place the two bars on top of a chest, laying about in his tent. Pan proceeds to take his chest back with him to the town he started and tries starting up an information business.
