In fact, that fits perfectly well - they're Powers who built something (western civilisation, in the case of the Olympians), but then never managed to let go of it.

You look at someone like Artemis, who wanders around by herself with the few people she likes - and you compare her to the Power we meet in A Wizard Abroad, who hangs out by themselves and doesn't like to admit who they are. It's a very similar approach.

Does that mean they're influenced by the Lone One? Well, to the extent that everything is, sure. But I think it's a mistake to project Michael onto all the Powers. The One's Champion is a very distinct individual, and is predisposed to a black-and-white worldview. We've barely met any other Powers (that I remember, anywise), but there's no reason to assume they're as... well, angelic, even if in the fire-and-brimstone sense, as the Champion.

Interestingly, the wiki identifies Michael with both Athena and Thor (and Prometheus, who has a role in one of the PJ series, I think). Having multiple avatars of the same Power bobbing around could make for a very interesting story - though I'm going to take a stab in the dark that this one does nothing of the sort.

... wow. That is a pretty textbook Gary-Stu. I gave up at the point where Artemis wouldn't talk to him until he swore not to hurt her.

Anyway, yeah, no. Doesn't look like it's bothered to consider the possibilities at all. I'm not honestly sure the author understands what the Lone Power actually did...

One exception to the Pantheon being influenced by the Lone Power that I'd argue--Hestia. She never really does much, but when she does, she seems to try to do right, without letting ego get in the way.
