Thaum Warping is a phenomenom where a being is mutated by excessive magic exposure.
When a living being is exposed to a large amount of Thaumic Energy, the energies somehow alter that beings physiology without modifying their genetic material itself, the result of this is that the effects can fade over the course of generations. The effects include altered body shape, the development of a Genius and the biologcal need for Thaumic Energy. Intelligent beings can manipulate and use Magic naturally thanks to this. Although it can happen during puberty and regeneration this usually happens in the womb or egg.
