I have been thinking about various quintessence sources and I was thinking on how a mage could reliably generate quintessence on a weekly basis without a node. The idea I came up with was a pastorship.
In MtA the idea of belief being power is emphasized quite a bit.
So what I want to ask is: Is it possible to make use of people's prayers in order to generate quintessence(or tass) and which spheres would be involved in such a quintessence production?
