Ah, yes. After the incident with the king, but before the apocalypse in Asuga, skirmishes began between different factions (in Mufigura, Jingo had become a protector by this point, by the way), and one of them was led by Professor Peleng. He turned out to be more complex than he seemed and used this artifact to build piloted golems – there was a cockpit for the pilot inside, they moved across land, and were very powerful. At first, nothing useful could be done with the artifact – it was just a weapon hanging on the wall, waiting for future events to unfold.
