Where are you in the game, in terms of main plot quests?
If you have the battle tower and returned to Broken Valley, what exactly is the problem? Can you enter the quarry tower? Can you talk to Williams on the top floor?
Have you installed the
patch?
If the tower is locked when it should be open, or Williams is missing or unresponsive, try emailing support@larian.com, with a description of the problem and a link to this topic.
