The term Intellectus refers to a mode of existence which allows instant knowledge of anything by merely thinking about it. Having Intellectus is a feature of various but few powerful supernatural beings.
The term Intellectus is used when a supreme immortal being is able to gain access to any knowledge needed. It is a mode of existence that for a few rare beings, allows them to view reality as one piece, place and moment. They no longer search for knowledge, they just simply know. They see the 'whole picture'. There are several loopholes. For one, the being HAS to know what they are looking for, and it takes many millions of years to acquire, and beings only have Intellectus on specific subjects; such as Demonreach on its island and the Naagloshii 'Shagnasty' on torture.
In the seriesEdit
- Main article: Turn Coat
The island Demonreach has Intellectus limited to its own shorelines. Harry Dresden receives a limited form second-hand from the island's genius loci. It allows Harry to know anything on the island, as long as he thinks of it.
According to Word of God(reference needed), the Skinwalker that Harry faced in Turn Coat has a limited form of Intellectus that focuses on how best to torture its victim. In the novel it abducts Thomas Raith because it knows that hurting him would be an effective way of hurting Harry, and that destroying the humanity of Thomas would be a good long term method of hurting him too.
