The Mermaid - She Creature - the lake outside that bar place

[randomuses]

It's a calm day outside. The wind barely rustles through the trees, and there's only the odd sound of creatures making their way through the forest. Even the water looks almost glassy, undisturbed.

That is until something breaks the surface, sending ripples toward shore - a tail, to those who would be looking, though ti's gone a moment later.

Of course, if you pay attention, it may happen again.
