Graves was going through a forest with the Shadows.

They were heading back from an outing when he heard faint sounds, so he narrowed his eyes, then held up his hand, looking over at them. "Spread out. I'll go check what the sound is." When he got nods of approval, he headed off to follow the sounds.

They almost sounded like singing, and when he got over there, he saw... well... something?

It looked like a person standing under the water of the waterfall, but something about them looked... wrong? It was as if their body was blending into the water of the falls, like they were one of the same. He squints and slowly moves closer, trying to see the creature better.

What the heck is this?

Who, or what, were they?
