"Most wizards don't know this, but we are a species from a different dimension known as the Underworld, you humans call it hell, we are the keepers of the portal to the realm that is housed within Azkaban, the reason we are here is that no Human should be able to physically touch us without dying, only one species within the three realms can do that and that is our Lord and his kin the Archdemons of the underworld the most powerful of the realm and considered royalty and you my Lord are the last of the species thus you are our King".
