From the introduction: You have been to some amazing places in your time. But now you arrive to one of the most unique places available to you. The Dark City of Commorragh. The most wretched hive of scum and villainy in the galaxy. A city where anything is possible for the right price and where pain rules all. This place is many things but it will be memorable, I assure you. Just remember there is only one rule here, no psykers. So you may want to cool it on the supernatural powers while you’re here.
