.Hack//Sign Ghosts in .Hack//Outbreak (Spoiler Free)

Throughout .Hack//Outbreak you can see fragments of the anime series .hack//sign (assuming that you've seen all the scenes at Delta Hidden Forbidden Holy Ground in Mutation).  Simply go to these places, in the following order, and talk to the ghosts.  You'll get items for this, but I'm not listing them.  You will get several Golden Grunties (permanently raises HP by 30) as well as several excellent healing items.  All of the places are root towns, so I'll just list the server rather than specifying that every time.

I have to tell you, this is a lot more fun once you've seen .Hack//Sign!
