Greatwater Lake on the verge of the rest of my life

Nikai wasn't sure if his intentions came across, but he smiled anyway as she answered with a few more words (though he wasn't sure if it could be seen all the way across the lake). She adviced him to shout off against the mountains and he looked over his shoulder at them.

Once her words had finished making their way across the lake, he turned to face the mountains. Nikai glanced over his shoulder in silent invitation for the fox to come closer so that she could hear what he was echoing better, and then he shouted as loudly as he could: "Echo!" And it bounced off — "Oh - oh - oh" — across the mountains ahead.
