The Spiral

The Spiral is a symbol of revenge for werewolves it has been used by The Alpha Werewolf on multiple occasions. It seems that it's primary use is intimidation or at least that is how the Alpha is using it since it has left it as a sign wether it be to frighten those it's about to kill (This was seen with the vet as he was called to look at a dead deer who bore the symbol) or for sending a message of some kind.
