Frostail's Japanese name, Inugami ("dog kami"), refers to the dog spirit with the same name. They are familiars conjured through a complex and cruel ritual in which a dog is turned into a vengeful spirit, that will follow its master's orders to protect them, or even possess people and commit crimes. They are however very dangerous, as their rage is all-consuming and can potentially turn them against the conjurer who created them. Families protected by an inugami are called inugami-mochi (Japanese: 犬神持ち,inugami-mochi), and will only marry their children to those of other inugami-mochi families.
"Frostail" is a contraction of frost tail.
"Nievacolas" is a combination of nieva (snows) and nueve colas (nine tales)
