"Well then, as long as I am not bothering you, I'll be happy to join." Tarentek commented, going back and forth between eating and disassembling his rifle as Onyx collected her pistols. Once his rifle was fully in pieces, Tarentek got up to look around for what he needed. Since Onyx did not use firearms, he did not expect to find proper supplies for weapon maintenance, but he knew enough to know some alternatives. It was not too difficult to find something that would work for basic cleaning, but it took some more searching to find something that would work as a lubricant. Luckily, Onyx's collection of cooking ingredients delivered what he needed, as grease worked as a fine lubricant. 

Tarentek started first on maintaining his own weapon as he ate. It was a task he had performed countless times, so it did not take long for him to clean and reassemble the rifle, after which he began work on the pistols. They were a common model, and he had maintained others like them before. Of course, there was no guarantee that he could repair even one of them. It did not matter how talented he was with the old technology if the parts to repair them simply were not there. He finished his meal, then cleared out the table in front of him to disassemble the pair of firearms, making sure to keep the parts for each separated. For one of them, it did not take long at all to determine the problem, as the trigger mechanism was busted. The other required that he take it apart fully, but the problem itself was actually something he had seen before, as it was a common point of failure for this type of pistol. It was not something he could repair without spare parts, but fortunately, there just happened to be an identical pistol right next to it. After about half an hour of examination total, Tarentek smiled once he saw that the parts he needed were still intact. 

"Ah, I think I have it." Tarentek said excitedly. "On this one, the trigger mechanism is busted; it won't so much as move the hammer. On the other, it looks like the recoil spring is worn down, which in turn put stress on the firing pin and caused it to fail. It just so happens, though, that the recoil spring and firing pin on the other pistol are in perfectly fine condition. I just need to swap over the parts, and it should work fine. Though, I suppose if you haven't used relics before, you'll need some practice if you want to start using it." He explained.
