It is said that there is an ancient being that travels the land on the heels of Saturalia spreading cheer. Long ago, this being liberated eight indrik from the demi-plane of Detritus to pull its sleigh and inspire awe in all those that lay eyes upon them.
What is lesser known is that this being actually freed a ninth indrik and enchanted it to become a beautiful woman to act as its companion. Over time, this enchantment has faded and so the companion becomes an indrik when out in the world and surrounded by nature. How she managed to gain her freedom and wind up in the frozen recesses of Skyrim is anyone's guess but, one thing is for certain, her master is likely not far behind.
