Cataclyst is a term for a Caster who was once a Natural, but Turned Dark. It's unknown whether they have the same powers and potential a Natural does. During their first few months as a Dark Caster, they will experience an uncontrollable draw to fire.
In The Book of Moons there's a passage:
"The greatest of the darknesse being the powere closest to the wold & the undyrworld, the cataclyst. The greatest of the light being the powere closest to the wold & the undyrworld, the natural. Where there is not onne there cannot be the othere, as withoute darknesse there can be no light."
- Elemental Manipulation: They are easily able to control the elements and the weather without hesitation. Their "go-to" element is fire and can start fires by accident called "The Wake of Fire" during the first few months as a Dark Caster.
- Time Control: They are able to control and freeze time, but it's very rare if they can.
- Reality Warping: They are able to manipulate reality with ease. So easy, even Sarafine was able to warp reality with Macon Ravenwood.
- Kelting: They are able to speak non-verbally with other Casters that possess the same ability. Kelting is extremely rare. Most Casters aren't seen to do it, only very powerful casters.
- Possession: They are able to possess other living beings and project themselves into the bodies of others.
- Dark Fire Control: They are able to control the Dark Fire in Darkborns and control them.
