You have the start of a really strong concept here! A world whose denizens don’t know it was artificially created as a sort of “seed bank” for intelligent life, about to find out the truth because of a corrupting “Darkness”. I’d love to see you add in more of the details you mentioned in the Discord, though I enjoyed the hints in the speech at the start. If names give you trouble, consider using titles - they can tell us both a lot about the thing they describe and the world or culture that created it.
