Being an angel wasn’t easy. Uriel would never look down on the others for finding themselves in a position where they felt incapable of doing the job they’d been born, or created, none of them were quite sure which is was, because they’d never been given a choice.

…doing the job for which they'd been…

They always said he’d had to strong a connection to the spirit guides he was supposed to just be watching over.

…had too strong a connection…

He was happy with the choices he made

…he had made…

older deities

So, in this universe they are not angels to a deity that is the only deity - their creator/father?

We don’t know why we created, how long we’re going to live, or even what we were supposed to do with our lives.

…why we were created…

maybe there is an all mighty creator being who made us and the first gods.

Ah, I see. ;-p
