A low rumble followed from the deepest recesses of the snake’s throat. The deep harmonic voice rolled out like a combination of clicking and singing, two simultaneous layers of lower and higher pitches. Air rushing between its teeth resembled the wind swirling between rocks. The words, if that is what the creature’s sounds were, all ended with a purring suffix.
“Keh-naw-nooooo. Gooooo-thooooo seh-nooooo.”
“It speaks? Is it speaking a language?” Kratos said.
“I think so. But nothing I can understand.”
