(Read author notes) Pansy was bit by while feeding what looked like a strange looking axolotl during her swim in a shallow section of the black lake to cool off from the summer heat. Since it had broken the skin and drew blood she decided to catch the creature and brought it and her injury back to madam Pomfrey and Professor Hagrid.
Years after the war, Severus Snape is forced to confront the unimaginable when a pod of territorial sirens claims the Black Lake. Among them is their leader—a monstrous yet familiar figure. His daughter, long thought dead, has returned, transformed and unrecognizable. (Feel free to use this and change to your own characters :] )
No one was meant to find out what she was. Humans feared what they could not understand, even when it was something divine. They tortured her, used her power, drained her until she was nearly dead, then made her disappear. Or so they thought… Now faced with divine retribution, what will Hogwarts do when faced with a vengeful angel.
