Try this site
www.themisive.co.uk for a walkthrough to Dungeon Siege. The site is called Walkthroughs Unlimited and look on the Downloads page, you want the Dungeon Siege Legends of Aranna walkthrough, it's in pdf format, so you will need Adobe Acrobat Reader to be able to read it (at least v6 or above), if you havn't got it, there's a link on the home page of the site for Acobe Acrobat.
