In Platonic thought the metaphysical buck stopped with the primacy of individuality. For free will, it implies that the closer you are to godliness the closer you are to liberation.
Proculus on Polytheism
'The One' is a pantheistic theology in a sense because there is no division between "creator" and "creation" — the gods are both the source and origin of existence and inherently, inescapably a part of it as well. And also obviously a polytheistic theology operating within a pluralistic metaphysical framework.
