I think too many of them are ancient powers from ages past, which separates them from the PCs a bit too much. There are some really cool ideas though, like the White Queen as a patron of witchcraft and evil magic that would still benefit people, drawing from the actual history of witches. I'm not so hot on them turning the coolest Icon into 'lady that sex appeals demons to death' though. Otherwise they're pretty unique takes that aren't as open-ended as the default writeups, but would work very nicely in a campaign.
