Overwhelming victory for metallurgy (yes it is metallurgy of course. No use hiding behind a finger, as we say in Italy).
The head of the militia pulled a very convincing argument, so the council decided to spend time and resources investigating the strange material the axes were made of.
The first step was of course the application of fire to the artifact. A large fire was built and the axe tossed into the middle of it. The haft burned very soon and we could observe an intriguing phenomenon: after a length of time, the blade started taking a red color. Using a stone spear we pushed the blade outside of the fire and went near to it: the color seemed to indicate that the blade had grown hotter. We experimented for days trying several sizes of fire and leaving the blade inside for various amounts of time. Nothing different happened.
We tried to cool the hot blade by tossing water on it and, after several attempt and careful observaiton, we noticed some tiny cracks had appeared on its surface. It seemed the material wasn't indestructable afterall. It didn't agree with sudden temperature changes.
The next thing we tried was to have one of the Wielder's apprentices apply his powers on the blade. To our dismay, his fire was less efficient than a normal campfire at the task. First, his fire didn't apparently burn any hotter than a normal wood fire. Second, the apprentice grew exhausted after only a few minutes of using his power continuously.
Our elders agreed we would need a warmer fire to continue the experiments, we needed to see what would happen with hotter flames. The only problem was, we could think of only two ways to obtain warmer fire, both holding problems.
A. The first way was the more readily available:
we could ask the Wielder to help us and use his powers. As he was much stronger than his apprentices, his fire surely would be much hotter.
The second way involved finding different burning materials. Besides wood, the eldest tribesmen and the keepers of fire could remember the gray-black stones we had found on the slopes of the Fiery Mountain. Problem was, we hadn't seen anything like that since we came on the shores of the lake.
Two solutions were proposed:
B. We could search for the gray-black stone in our area, scouring the shores and the hills for it. It would take time and would not give us any assurance of success, but it was safe.
C. Otherwise, we could mount an expedition to the Fiery Mountain. The smoke was still occasionally rising from behind the hills, but much more rarely than in past years. Some said that no stone could have survived the conflagration, but others thought the attempt at least worthy of a try.
Alright. Get voting. Unusual update time, I know, but I was free this morning so took the chance to write this. Thanks for your patience, you will have at least one day to vote (most likely more, I'm still overwhelmed by work).
As a sidenote, metallurgy (if you can get it to work) will of course take time, so don't expect to kit your militia in iron plate anytime soon.
I will most likely post another interlude soon(tm) to describe the current state of the tribe, haven't done it in ages.
On another sidenote, Jesus. CYOAs have popped up like mushrooms in the last week. Lots of competition. Hope I don't lose too much audience.
