Doctorinecasting

A form of magic where the user of immense conviction is able to bend reality so long as they truly believe it. The use of which can forge or dissolve metaphysical laws for brief moments in their vicinity. Belief must be total, doubt is fatal. Typically accompanied by confirmers, a group of people with belief or altered memory that affirm the belief allowing small leniency on the part of the caster. Very powerful but high risk, can cause Schismatic Implosions resulting in the user imploding both physically and spiritually or in Ideophantasms when they die where the belief continues to walk long after the user has died.

the Solaran Emperor is believed to be one due to one advisor who was found dead claimed they were able to manifest the will of his people seemingly into production towards their goal. Though this is debated as it was a piece of information traded for asylum.

Most Major factions use them in order to achieve the impossible for smaller factions and some cult leaders are said to have used it. Though sadly failing to hold the doctrine erases memory of you so there are more that you should know but dont due to that.

Technically some believe the first Contemplative was one but again they're hard to verify as skeptics can usually claim it was something else unless they erased themselves in which case they aren't remembered
