Not sure if this will be of any help in restoring any lost content (provided lost content is wanted). http://web.archive.org/web/20080822011237/http://terra-arcanum.com/ I do kinda miss this locations section and the character planner. Well, honestly, I miss a lot of it.
The character planner moderately works still. I do like the old fan fiction which can still be accessed from the archive, those stories are interesting to read. Also, I found Amtut again, which I hadn't seen for a long while, until recently. There doesn't seem to exist any obvious link to it elsewhere on the page, so I thought I'd put it here too. http://terra-arcanum.com/amtut/
