Thought Projection (思念体 Shinentai) is a Caster Magic.
A type of Magic which allows its user to create a psychic copy of his or her body. This Magic can work even over great distances, allowing the user to essentially be in two places at once. While some Thought Projections are intangible like holograms, used merely for communication, Jellal Fernandes is able to create a particularly powerful Thought Projection that can physically interact with people and objects, even though it lacks physical form. This allowed Jellal to essentially live a double life and trick the Magic Council into thinking that his Thought Projection was his "twin brother", named Siegrain. The creation and maintenance of this alter-ego is very taxing, essentially halving Jellal's overall Magic Power; however, once the Thought Projection reunites with the body, the Magic Power returns to normal. The Council itself uses Thought Projections to appear in regional branches to attend official functions; thus, furnishing the necessity to leave their main headquarters in Era. It is possible for the user to make a thought projection of themself at a younger age, as demonstrated by Ultear.
