Wraiths and Ice Wraiths 

Unlike Wraiths, which are Ghouls in the lower 48 states. Ice Wraiths are a different type of Ghoul, exposed to the Radioactive Snow. It's skin is  blueish glass like translucent skin showing the bones and organs. It's touch is cold as ice. They are just as intelligent as their normal counterparts just standoffish, they're not any more hostile. They have a low tolerance for heat and often stay in dark locations away from the summer sun.
