Cold, anxious, and considerably alone, Arianwen had no place to go. A great hurricane swept her home next to the seashore. Storms normally bring nothing good, and for Arianwen, this was the case. Her parents, her friends, pretty much everyone she knew had been taken from her and the eleven year old had no idea what to do. Until he showed up. One night, Arianwen went to the surface, in search of some sort of contact with another person and she was not disappointed. She met a man named Albus Dumbledore, who was compassionate toward the small girl, and offered her a home at his school. Naturally, she agreed, having no where else to go... after being at Hogwarts for a good while Dumbledore warns the small girl that students will shortly be arriving and that if she didn't wish to attract any attention, she should stay underwater. But after Sirius Black comes across her, he finds her to be quite unlike the mermaids that are normally found in the black lake. Resulting in his new personality trait of gentleness. The two form an invincible and rather out of the ordinary friendship.
