The cave wasn't narrow. On the contrary, a Giant Dragon could pass through it without any obstruction, a testament to just how spacious it was.
Ronin observed his surroundings as he walked. He noticed that the walls were perfectly smooth, as if they had been specially polished. There were also lighting fixtures mounted on them, and the purplish-red glow he had seen from outside the cave at night was coming from these very devices.
"Magic Crystal Lamps?"
Ronin took one of the lighting fixtures down from the wall. Its shape was different from the Magic Crystal Lamps in Wushan Castle. 'I wonder what the internal structure is,' he thought.
"These lamps go out. I've often seen people take them down, pour Energy into them, and then they light up again."
Carlos recounted what he had witnessed. "Over the years, I've lost count of how many times Natalia and the others have done this."
'A rechargeable device?'
Ronin's eyes lit up. "Elron, take a couple of these back with you to study."
