Way of the Flow monks, manipulate the way of existence, nothing is free from their manipulation, not even the weakest powers of gods. 
These monks when in high enough numbers are to be well respected and not to be trifled with, thankfully they only step into conflict when it is brought to them or if the conflict is threating all of reality.
Their mystical control of the natural and magical flows are highly respected from all beings.
