Alchemist

Those of the writer’s craft are Alchemists; their spells and transmutations from a piece of paper and blots of ink transmute the mental realms of people, potentially changing their perception, which can fundamentally alter the world and Reality.

Moving on from the mental realms, the Alchemists were not far from the Truth in that you could turn any metal into Gold but that would require tremendous amounts of energy to change the atomic structure of the atom’s components (neutron, electron and proton numbers although methinks you could manipulate the Quarks to do this) and that the Gold itself would be radioactive.

Another idea the Alchemists had was trying to find the Elixir of Life to grant immortality which is not far from the Truth as with Science, understanding more about DNA and how to manipulate it to extend our lifespans along with harnessing immortal cancer cells to our benefit, we could in theory make a concoction that would manipulate our genes to grant life extension.
