Because he is the only god, the Dark God's worshiper alignment restrictions are more relaxed (I'll edit this into his writeup). So CE is fine in that respect. However, I tend not to like CE PCs just because they don't usually play well on a team, at the very least because they tend to piss off the non-CE team members. NE is much more team-friendly.
Jack, I just noticed (while splitting threads) your question about a Warlock's EB and Quicken SLA. I've just checked out Tome of Magic and for some reason there's no Quicken Su feat... I'll put into the houserules that EB still counts as an SLA for feat purposes.
Osle, where's Skaven posted?
EDIT:
Hey Jack! Ask, and ye shall receive. It may need some tweaks, but there's your starting point.
