The Beldam

 The beldam, best known as other mother to her victims, is a shape-shifting entity who can transform into any mother in order to lure kids into the other world and eventually keep them captive. In order to entice and lure her victims, she creates beautiful things in the other world that contrast the dull and boring things of the real world. After ingratiating herself with her victim, she convinces them to let her sew buttons into their eyes in order to consume their lives and steal their souls.
