These are a little different as well, yes they require blood for offerings but they travel in snow. their body is ice cold no matter how much warm blood they get. There is nothing you will ever do to make their body warm. and that is how they manifest as well during cold weather and cold chills. Now if you choose to bring one home there is something you must know, they will always be with you but during summer months they will reside at the north pole for obvious reasons. They have the ability to freeze anything hearts, finances, jobs anything at all. they are amazingly powerful and dangerous.
