Sorry, but I haven't gone onto the site for long time, so can someone tell me about the throne of bhaal, and when its coming out?

You're in luck, check out the front page today:

There have been a few news items over the last few weeks that you might want to chase up.

Also be sure to check out the Throne of Bhaal features I'm putting together and updating regularly.
