English to French Art/Literary Poetry & Literature teenager's fantasy fiction

"In this world, after death you are greeted by a never-ending line, at least the humans are. Im-Potent granted us souls he can play with. The dragons don’t have them. Dragons hate to be reminded they were created as the first mistake, to be replaced by humans, the second mistake. If you really want to get under a dragon’s skin remind them of that."

in the book, Potent is the name of their god, which I translate in the first volume by PUISSANT.
This sentence is in the first chapter , where the author makes a quick reminder and exposes the new situation of his heroes.
Im-Potent : I'm Potent

I don't have a clue about a way to translate it without betraying this pun.

Any idea
