By sheer force of will.
The word fiat is not about money. The latin it comes from means “let it be done.” A command or act of will that creates something without or as if without further effort. A spell.
According to the bible, the world was created by fiat.
You may be familiar with the world in the context of currency. That is, money backed by nothing. Fiat money is a medium of exchange by virtue of our insistence or shared belief that it holds value. A spell.
I am interested, now, in testing the limits of my magic. So by sheer force of my will: Let it be done.
