Adventurer: Pannar Problem

The Pannar control several castles that formerly belonged to the most advanced planet civilization. The Pannar operate out of the castles and patrol the road along which the medicine plant is delivered to the castle where the Keegor space travel device is kept.
The Pannar knights carry local iron swords, small shields and wear thin iron breastplates. Apparently the local metal workers aren’t up to producing plate armor or even the very large chain mail outfit a Pannar warrior would need, at least not yet.
I can see how to defeat the Pannar and earn some new technology for Merchant Adventurers from the Keegor.
The Keegor are much more intelligent than I am. However, as strange as it might seem, I’m smarter than the Keegor. Thus, the Keegor rely upon their intelligence to solve problems in the long term. I have to use smarts to solve problems in the short term. I also have to risk my life. That’s why I earn the big bucks.
(Okay, you went to school. You think you learned history. You memorized the date when Columbus ‘discovered the new world.’ You also learned the George Washington could not tell a lie and he chopped down a cherry tree. Both items are total lies. Neither item will ever be of any real use to you. However, you treasure the ‘learning experience.’ Why is that?)
(Let’s review some useful history. Many times, in the past, warriors have conquered other peoples, mainly by using new technology or ideas. Once they conquered the people, the new local rulers then antagonized the conquered people until the slaves arose and destroyed the conquering forces. Why did the conquerors send in blithering idiots to run their newly conquered lands? Because no one wants to go and live among the despised, lower class conquered people. Thus, the conquerors chose stupid, greedy people who went and oppressed the newly conquered slaves until the slaves revolted. An enterprising merchant adventurer is about to speed up the process of the slave uprising.)
(In the ancient world of the oriental East, there were priests who were forbidden to carry weapons, but still found it necessary to travel bandit infested roads in the course of their religious duties. Thus, the priests developed unarmed combat systems that enabled them to defeat an armed bandit. However, several armed bandits at once still posed a problem for one lone priest. Thus, the priests developed ‘non-weapon’ weapons that got the job done. One of the non-weapons is called a ‘meteor hammer.’ The meteor hammer is just a couple of weights at the end of a longish rope or chain. The meteor hammer isn’t obviously a weapon, but an old time priest, after much training, could use his meteor hammer to defeat a skilled swordsman or multiple, less trained opponents.)
I get the Marines to obtain for me an advanced technology meteor hammer. The weights are very dense, very strong ceramic items and the ‘rope’ is a very strong synthetic that will resist being cut by the crap swords the Pannar knights will have. I also get a very thin synthetic cord of incredible strength and some infra red motion detectors.
I also get the Marines to obtain for me a ceramic breastplate and a ceramic helmet. The breastplate is lightweight, impossibly strong and even breathes a bit, so that I don’t cook while I’m wearing it. The helmet is made of the same stuff as the breastplate and it’s not only strong, but also makes it almost impossible for a viewer to see my face. The helmet also has a Keegor supplied light built in. With the light, I can see in the dark, while my opponents can’t.
I buy a very nice, re-curved fiberglass bow and hunting arrows from a shop that specializes in archery equipment.
Finally, I get a simple, but special throwing star from a local Kung Fu studio. I have the throwing star coated with a poison that government scientists obtain for me.
