"Truthfully, this lowly one doesn't know exactly what the blue gem does," Hammock explained respectfully, "but I've heard it can open up some passageway. I've seen it used by two-eyed beings like yourself."
The head's eye never left Reeva, filled with a mix of fear and reverence.
"Do I need to exert some mystic force to touch that thing?" Reeva asked, curious about how to proceed. Originally, he'd intended to snatch the gem and run, but now that he had someone knowledgeable, he wanted to confirm a few things.
"Great being, everything in this place contains some mystic force. If you wish to interact with your surroundings, you need to exert some of your own," Hammock replied. "That's why a Hollow like myself is considered a lesser being."
"Hollow?"
"Just a term for a lowly being without mystic power," Hammock explained, eager to keep talking with Reeva.
