There used to be a good map resource site by Orange & Moe at:
However, it seems that it is now currently down. I do have all the maps from the site compiled nicely into a big text file. Is there a file section on this site that I can upload it to? The maps are not completely up-to-date and many new areas are missing, but those sections which are still good is excellent for exploring. Trying to look for secret doors are boring and DTs are frustrating when you are a newbie. These maps show them all. A great help for anyone who is just starting out, or even new 50/50+ characters.
