eternal echo

Exploration Stage: House on the Reef
From: Huntress
Description: Do we need anything else for Insu and Inhyo's voices? Oh yes, what about echolocation? I'm sure that would help. But in that case, we'll need my sonar... where did I put it?
Completed: Thanks for finding Thorner! There's a reason this is shaped like a narwhal. Did you know? The narwhal has better echolocation than any other creature. With it, they should be able to navigate the celestial seas without relying on their sense of sight.
