"The 'Prototype of Truth' is the Book of Truth, and really, there's no active way to obtain it except by luck," thought Annan.
But as the newly appointed Charioteer, Annan was Salvatore's only friend, so there was no need to worry about this at all.
The remaining concern was the "Cycle of the Four Wheels"... his very own perpetual motion machine.
Of course, even though it was called a perpetual motion machine, its requirement was not to "extract power from the world," but rather to have its own independent energy source. It didn't matter if the scale was not very large or if in the distant future it would be exhausted.
It simply needed to be manually replenished.
For example, the energy produced by the souls that powered the "Death of a Nation" to move skeletons was his "Cycle of the Four Wheels"; and the energy generated after their souls were purged became the "Cycle of the Four Wheels" necessary for Pardoners to become gods.
