“A grand, old, audacious thing, built right into the side of the cave?” asks Cang, to which Old Mossy nods readily. “We have had occasion to encounter it,” he continues.
“Did you hear a knocking?”
“Pardon?”
“A knocking, like this,” says Old Mossy, rapping his fingers on the flat of his palm to make a soft slapping noise. “Well, sort of like this.”
“I don’t think we heard any knocking,” Shyan says.
Old Mossy’s eyes take on a haunted look. “Strange, that,” he says. “Last I was down, I heard a knocking, as though from the other side.”
The princess squeezes his hand reassuringly.
“A knocking, and a deep voice, calling my name: ‘Asmosius…'”
