Banshee was really the beginning of the doll project and the first LittleDeadSin I came up with. He actually evolved as the familiar of a character Sybella, and I ended up taking this idea and expanding it into my LittleDead world. 

Each LittleDeadSin is connected with a character and they play off one another. 

Sybella is Quiet Supressed Anger. She is the softly seething serpent, waiting for a chance to strike. Banshee is her opposite. He is loud and abrasive, quick to take offense and argumentative. He doesn’t suffer fools gladly, and he says exactly what he feels.
