It’s all a bunch of timey-wimey wibbly wobbly… nothingness. I don’t exist properly in time, nor does Provenance. I simply establish a bit of cause and effect for the benefit of those who hail from planes with a temporal dimension. It doesn’t make sense to anyone without nigh deific power or who doesn’t live on a timeless plane himself. For instance, no one ages while inside Provenance, when I view other dimensions, I can see nigh unto everything, and when I return people to their dimensions, I can send them just about anywhere and anywhen.
Properly, Provenance never began, and will likewise never end.
