Shadowfang Keep Unplugged.
Our very own World of Warcraft team has produced a guide to Shadowfang Keep. They mentioned that they wrote this:
"Being a low level and small instance tactics are fairly easy to master in Shadowfang Keep.
At the beginning of the instance, go in to the room on the right of the entrance as there is no way to raise the gates, don’t bother trying. The monsters here are a low level and should be fairly easy to pull and kill. Continue up the stairs and down the passage to a locked door. If there’s a rogue in your party he can pick it, if not you’ll have to let out the prisoners that are down the stars to the left of the room you are in. Not sure why they are locked up if the have keys, but there you go. To release the prisoners pull the levers by their cell. Through the door is the courtyard."
