Belief is one-sided affair. People believe and gods may decide if request will be fulfilled or not.
But what if people and gods could regularly cooperate? What if gods would ask people for help?
Example: The Visitor gave Meadowers (those, who were known as Arch-trees and Arch-animals) all his knowledge and so they did not needed to ask him for help, at least for very long time.
When he died, civil war (later known as War for The Visitor's legacy) took place in the Meadows - and one of its results was that Arbich asked The Visitor for taking leadership of all Meadowers. The Visitor accepted - and became wedding officer and high counsellor. So, Meadowers could ask him for judging their quarrels.
But under one condition - they will do what he ask them for. Meadowers accepted The Visitor's condition - and so they are ready to do what he ask them for - and he fulfilled role of judge in some cases (... later Meadowers became solve their quarrels without help of The Visitor, because they found it easier and faster - as he wanted).
