So Eridians use echolocation and sonography that allows them to hear through solid materials. And we know that Rocky can basically hear the whole Hail Mary without problems.
We don’t know much about planet Erid beyond the very basics, but planets that have iron core usually feature volcanic activity and therefore magma and other materials movement underneath the planet surface.
So considering this…
Do you think ancient Eridians ever lied down on the ground to listen to the voice of their planet? Keeping very still and waiting for a faint and distant sound from down below to reach them.
I would imagine that to be possible mostly near the volcanoes, where magma comes closer to the crust (planet surface). So do you think those ancient Eridians were coming to the fire breathing mountains to listen to planet’s songs?
Did they consider their planet alive in those long ago times? Maybe they worshipped it as their creator and parent? After all, their bodies are so similar to its. They sing to each other just as the planet sings to them from time to time.
Imagine Eridians’ one and only ancient god being the planet itself.
