"Fire. The words do not exist to describe the beauty and the power of fire. Pyro would invent words to do the job, but this is unnecessary. Fire is already the best form of its own expression. Why be a poet of words, when you can be a poet of fire? That is what Pyro says. And that is why you will want to be a sorcerer, an artist with the flame." – The Manual, The Book of Pyro
The list of spells is composed of three types of spells: the spells used to summon the Proles, the actual wizard spells granted by Pyro and the spells that every god's wizard needs to have to function.
