I believe their role in the universe to be that simply of wonder. A species so at one with their own dimensional elixir, that they need not concern themselves with our trust, nor our acceptance.
Imagine yourself showing a previously blind man around a temple made of living flowers. Would he care about your intentions?
If what I considered to be a less fortunate entity. Less fortunate in the sense of the misery from the dimension in which they inhabited, came breaking through into my timeless paradise I would welcome them with open arms. Being aware of their linear grasp of time, and the hollow pursuits to which they soon would once again be bound. I know that I would use that time with them wisely.
To not mutter vaguely into the ears of an inaudible brute, but to take their hand and guide them. To show them boundless infinity, and leave them knowing they can return.
I'm not for one second saying the entities I encountered are totally benevolent. I'm just saying that on every occasion I've spent with them, this is the sense that I got.
