"That's a question I'm only beginning to puzzle out an answer for," Sir George admitted. "As nearly as I can tell, there is some authority to whom all of the guilds must submit. Whether that authority is what we would call a government or not is more than I could begin to say from what I now know, but its decisions appear to be binding upon all parties. Apparently, it apportions grants of authority in matters such as this to maintain order among the various guilds, and the consent of someone native to this world is a precondition to obtaining its permission to mine here."

"And he doesn't expect whoever has just lost the rights to this world to complain to this authority that he's poached upon their preserve?"

"Apparently not. Again, it hasn't been explained to me because it wasn't something that I had to understand in order to discharge my duties, but the `Commander' seems quite confident that the new agreement will supersede the older one beyond any possibility of successful challenge."

"So his guild will simply take over everything which had belonged to its rivals? And even if it does, how will they prevent anyone else from trading with the natives in our absence? From what you've already told me, he clearly doesn't intend to stay here to enforce the terms of his new agreement, so why shouldn't anyone else with his advantages in technology simply arrive here and demand that the natives trade with them? Or, for that matter, lie to the natives and claim to be representatives of the `Commander's' guild?"

"I raised the same questions with Computer," Sir George said. "To answer the last one first, he told me that the natives will never have the option of trading with anyone else so long as the current agreement is in force. Something he called an `orbital traffic monitor' is permanently stationed here. He says that it `orbits' the world, which—if he is to be believed, and by now I see no reason not to believe him—means that it actually travels in a permanent circle around a round planet. However that may be, it contains still more of these people's technology, and the `Commander' will place a copy of his new agreement aboard it. All ships approaching Shaakun are required to report their presences and identities to it, and it will inform any other merchant vessels that the `Commander's' guild now has exclusive trading rights here. That notice will warn them that any attempt by anyone else to trade with the natives is a crime which carries very heavy penalties. As I understand it, those penalties may range anywhere from heavy fines to outright confiscation of the violator's vessel."

"But if it's unlawful for anyone else to trade here in violation of exclusive agreements, then hasn't the `Commander' himself violated the law?"

"Not according to Computer. The `Commander' comes from what is obviously a very ancient civilization, my love. They have highly developed laws and customs which Computer says govern every aspect of their lives and business arrangements. The `Commander' himself isn't taking a single pound of ore with him when he leaves, and technically he hasn't `traded' with anyone on this world. All he's done is to... negotiate a new trade agreement which makes it legal for his guild to trade here henceforth. All of the ore which has already been mined and processed under the pre-existing agreement belongs to the guild with whom that agreement was negotiated, and it would be illegal for the `Commander' to take any of it. But when the other guild's ship arrives to collect the ore which has been mined since its last visit—and Computer says that ships call here only once every fifty or sixty of our years—it will be illegal for that ship to take any of the ore which has been mined since our agreement went into effect. Any which had been mined before our arrival will belong to the other guild, however, and the `Commander's' guild will be required to maintain very careful records to ensure that none of the other guild's property is molested or misappropriated."

"It all sounds very complicated," Matilda sighed.

"I certainly can't disagree with you about that," Sir George agreed. "But Computer insists that their customs and traditions are so binding that no one would even consider violating them. Which doesn't mean, so far as I can tell, that they won't search diligently for any loophole or technicality which might permit to them to violate the spirit of a custom or regulation so long as they can do it in what's technically a legal manner."

"In that much, at least, they seem very like humans," his wife observed, and he chuckled sourly.

"In some ways, they are very like us. In others, though, I find that they become more difficult to understand with experience, not less."

"I suppose that's inevitable, given the huge differences between us and them," Matilda said. "Still, it occurs to me that if the `Commander' and his guild can compel the Thoolaas, or some other tribe, at least, to cede the exclusive trading rights for this entire world to them without technically violating their own laws, then surely someone else could do the same thing to them."

"The same thought had occurred to me," Sir George replied. "I asked Computer about that possibility, and he admitted that it existed, but he seemed unperturbed by it. For all I know, that indicates that it's not unusual for trade agreements to be changed in this fashion. Since they wait fifty or sixty years between visits here to collect the ore anyway, perhaps it's simply that the amount mined between visits is sufficient to pay for all the effort the `Commander' went to in our own case."

"And still neither he nor Computer has explained to you why they needed the swords and bows of you and your men instead of simply using their own weapons?"

"That they haven't," Sir George confirmed, and his tone darkened once more. "Nor, I think, will they anytime soon. But whatever the reason, we seem to have demonstrated our value here conclusively. From what the `Commander' and Computer have said, the guild will require our services for the same purpose elsewhere soon enough. And, as I said, the `Commander' has already expressed his gratitude to me. I understand that he'll be expressing it personally to the men sometime this evening."

"I see." The change in his expression and voice had not eluded Matilda, and she cocked her head at him. "And has he suggested some means by which he intends to make his gratitude manifest?"

"Indeed he has." Sir George looked into her eyes. "He intends to reward us with two more weeks here on Shaakun... before he returns us to `stasis' for the voyage to our next destination."

Matilda inhaled in quick dismay, and he reached out to capture her hand and squeeze it tightly.

"I could have wished for longer," he said much more lightly than he felt, "but at least you and I and Edward will have those weeks without the press of constant negotiations with restive chiefs or worries about taking the field. And it wasn't as if either of us ever thought that we could stay here forever, you know."

"No, but—" she began, then stopped herself.

"I know," he said gently. "And, truth to tell, I was surprised by his generosity. I don't know how long he originally expected to remain on this world, but I know it was nowhere near the time we've actually spent here. He feels the pressure to move on, yet I believe we've convinced him of how much we value our time in the open air outside his ship. And I believe he's come to truly value my counsel as well as my battle skills. Surely, in the long term, that can't be a bad thing, whether it be for us or for the benefit of the rest of our people."

"No, of course not." She drew a deep breath and smiled at him. "Indeed, my love, I am prouder of you now than ever I was on Earth. Certainly none of the King's other captains have ever had so intricate a measure to dance as you!"
