Lorelei

Lorelei had lived her whole life by Lake Brock in Beguile.  When she was a child, one stormy day, the waters of the lake had almost taken her.  Lorelei had wandered down to the shore alone, walking along the smudge of sand and had been captured by a ferocious, hungry wave. She had struggled against the water as it dragged her tumbling beneath its dark tumultuous depths. 

Just as it seemed as if her last breath had been stolen from her body and she had succumbed to the cold waters she had felt herself being cradled.  The arms had thrust her up from the depths of the water and carried her safely to the shore. 

She insisted that she was rescued by a merman that came from the waters of the deep lake and bought her to the shore.  The townsfolk of Beguile had long since tired of her stories and were not at all surprised to find Lorelei at the shore of the lake gazing into the water expectantly.
