You let out another chirp, and you're waiting to see if this echo response will be louder or smaller than the previous one. There's silence for a few moments, then the echo comes back; it's much louder. That echo is right by you now, you can feel that Hades is nearby. What does the increasing volume of the echo signify?
a) Hades is far away.
b) Hades is approaching.
c) The chirp was too loud.
d) Hades is not present.
