Many homunculi were created by the hyperboreans using the formulae of life left by the Old Ones. But those sorcerers could not fully grasp the runes of the Old Ones and their creations were as imperfect as their understanding, thus were a great many abominations abroad in the land and some abide even unto this day, undying and hideous to the eyes of man.
(From The Necronomicon of Abdul Alhazrad)
