I love it. Truly, it's a great idea... but it seems too much like just a psion theurge, or whatever, rather than being a different kind of alienist- the only abilities it grants, other than dual-spellcasting progression, is saves (leading to immunity) to spellcasting, and you and your familiar get the pseudonatural subtype. And then a couple of rather plain abilities. But enough of my complaining; it's still cool. And that picture of the warforged is awesome... source?
