Reading the latest TSA books, it's clear that the Hundred Gods have a very limited perception when it comes to Eärwa (not only blind to the No-God, but presumably to all soulless creatures). Also, they obviously need earth-bound agents to enforce their will on the living.
And where is the creation myth? Your series is so full of religion and religious metaphysics, but so far there's no reference to how "it all began". Who created the human race? What is the equivalent of Adam and Eve, in a universe where religious scripture is an objective reality? It seems that the Hundred didn't create humanity after all, and they're more like extra-dimensional parasitic demons than "Gods" in any traditional sense...
