Cam Banks was wrong about the Fiendish Codex I "getting Krynnish gods' alignments wrong," since it didn't list their alignments and you can't assume what their alignments are based on what plane they dwell in. There was no part of his statement that was correct.
I do think the idea behind the new Dragon article, with the time loop in Istar, is a pretty nifty one. I don't mean to be entirely negative, although the "xenophobia" (using the word tongue slightly in cheek) that inspired it is annoying to me.
I'm sure it's a great article.
In 2nd edition, Chemosh was LE and he lived in the Abyss. He could just as easily (or, really, more easily) be NE and live in the Abyss. Fiendish Codex I didn't rule on which was the case.
