Original Description:
 
As always made by the wonderful MinamiKoboyasy (love ya!)
 
So this is inspired by Acteon and Artemis. In the myth Acteon peeped on Artemis skinny dipping with her maidens and was punished to be transformed into a deer to be hunted by his own dogs. Hence why the moon (Artemis is a moon goddess but not the personification which is Selene-Selune Darkeye reference :D) and the deer in a lake/pond.
