I really liked the Prince of Nothing too. I liked how Bakker described spells as songs that are sung, it was a nice image.
Also, it was interesting that Kellhus could use more then 1 inutteral string, at the end of the Thousand-Fold Thought, after meeting with Moenghus, he alters a more conventional spell, I forget what its called but it allows remote telepathic communication between Mandate Schoolmen, and with 2 inutteral strings creates a transposition spell to teleport to the battlefield.
Also, the difference between the Mandate and other schools, the Gnosis and Anagogis were in their philosophies of spell-casting it seemed. The Gnosis was the "Philosophy" while the Anagogis was "Poetry". The Anagogis would create ethereal dragons and suns to affect the material world while the Gnosis dealt with abstracts and manifested as geometrics and energies.
And the Gnosis looks to be stronger by an order of magnitude. Achamian, who'd been having a rough time of it towards the end of Thousand-Fold Thought, ran across that Imperial army, and decimated the army, the Imperial Sukh School and killed their Grandmaster. By himself. And Kellhus annihilated the Cishaurim.
And of course the Cishaurim use the Psukhe, which is an emotion based magic apparently... They use the "Water" they bear within them to affect the world.
And then there is Techne, used by the Consult, it appears to be basic biology, genetic engineering and such. But I don't really know since they are left rather mysterious. Along with the No-God, whatever he is.
Anyways, I'd like to get the Judging Eye at some point too. But I've heard it isn't as good as Prince of Nothing, so I've been waiting for my library to get it.
