Faith is a very mysterious thing.
Gods do not actually need the faith of people, nor do they gain power from it—gods always gain power solely from their own "purity." Conversely, it is often the believers who need the gods, because people will always experience moments of confusion and emptiness, and each god can be seen as a path to the supreme and perfect, a direction worth pursuing.
After all, on the Path, the gods are the pioneers at the forefront.
Of course... that doesn't mean faith is entirely useless. Faith is a "feeling," a direction pointed by the minds of sentient beings. Although it cannot be directly manifested as "power," it can provide a bit of support in the mind. However, conversely, if faith becomes too robust, the object of that faith might also become shackled by it.
Ybur carefully savored the faint faith directed towards it.
What was strange…is that this "faith" hardly had any directionality, it merely gave it a sense of being trusted by someone.
