Seal of Obedience

This seal is placed on the throat of Nyx's pets and employees. It looks similar to a collar, with the following symbol on the front. This "collar and symbol" are visible under fur, on fur, on scales, under scales, and more. The marks can not be removed by any one other than Nyx. This is created via Blood Magic only requiring a single drop of her blood to place it.

For employees, it just shows where they work and that they are under her protection. It can deliver mild shocks as punishment if something is done wrong.

For pets, it shows that they belong to her. Upon placing it, it delivers a much larger shock, showing that they will be punished if they disobey her.

Other powers it can do are as following:
generate a leash
Mild forced command following (it generates a mental pressure to try and force to obey)
