According to the official website for Deborah Harkness’ All Souls Trilogy, daemons “are creative, artistic creatures who walk a tightrope between madness and genius.” They have an extra chromosome, but their origins are shrouded in mystery. Daemons have “glimmerings of supernatural power,” but they can’t enchant objects like witches can. Some daemons have reported precognitive visions and telepathic abilities, “though these readings and visions, like daemons themselves, are not always reliable.” At puberty, daemons’ traits come to the fore, either as mental and creative brilliance or as madness, “and even, in a few regrettable instances, murder” .
In summary, daemons in A Discovery of Witches have creative and artistic abilities, and some have reported precognitive visions and telepathic abilities. However, their powers are not as well-defined as those of witches and vampires, and their abilities can vary greatly depending on the individual daemon.
